Help me Please!

a little background on me...im 27 and been in love twice. i have 2 kids age 9 and 11.what i need help with is a broken heart thats so hard to get over.I have talked to family  and friends for advise. i still cant get over this.this is a long story. i feel   i have to start from the beginning so that u can understand. i started this relationship with this person.Im the beginning it was ok. We started as friends. casual dating.I waited a month before we had sex.So they ask for a relationship and of course i said yes. In the process i was going through some finances problem. So my kids and i moved in with this person. From the jump we had problems.My brithday came around and this person and my friends threw me a party. My exes and other friends who were attracted to me attended. One of my gifts was a ring, from the one who was attracted to me.Always knew this person was attracted to me,but never gave them the chance. Because I wasn't attracted to them.Anyway they had a ring for me and i accepted it. I was showing my friend the ring, One of this person friend seen me.Went back and told. So the party went bad.This person left me at the party.So i ended up staying over a friends house until the next morning,My friend took me home.When i got there.This person was so heart broken that they told me to pack my things up and get out.So i did.I moved in with a uncle. We didnt talk for about a week. I called up and tried to explain and ask for forgiveness. So we started dating again and i was going over there for the weekend. They ask me to move in with them.Said they will never put me out again. Came to my uncle house and pack my things up.So i did.In the beginning things were fine.Remind i said in the beginning i had my heart broken twice.So my ex of 4yrs. Got contact and we started communicating again. Being the flirt i am.We started flirting and made plan to meet up at a hotel.I thought about it and I thought,Well in ended up texting my ex that we need to be friend that im in a relationship and it wouldnt be right.Not noing that checking my phone and find out about it. So we solve that problem. Things was going good.Making plans for the future and they helping with kids. We was a family.But we still had days where they was distance and wouldnt talk as much. Anyway i didnt do much around the house because of my schedule at work. So  dinner would be done by the time i got home,Anyway it was time we got in a agurements and they would tell me they was unhappy. So this person started going to school full time and working full time. I had to pick up at home. Which i did try to do.One thing i did keep the house clean. Anyway in the process me ex for 4yrs came and said they want me back. i told them no. But I still kept contact.This person didnt like the fact that we were still talking. And i told them i wouldnt stop.Cause i wanted to keep the friendship.The last problem we had the broke the relationship up was. Oneday I went over a friends house that is also friends of my ex of 4 yrs.I dont no if i mention that my ex lives in Chattanooga,Tenn.So i was there and walks in my ex of 4yrs. So i called this person to come get me from there when they got off work.So when they get there. They walks in and walk back out. MAD! So we argue about it. Tried to explain i didnt no they was going to be there and etc. So the next day I had to go to work. I got off early. My ex of 4yrs ask me to see them off. They was going home.So I said yes and that was my oppuntunity to tell my ex of 4yrs that we would have to stop all contact.Because keeping friendship was causing confusing.And thats what i did. The next day leaving out i left my phone at home and this person go through it.And they ask me did i go see  my ex off and i lied and said No.They ask more then once and i kept lying.Reason is because i didnt think they would understand.So they ened up telling they went in my phone and knew i did.So me tring to explain.So days passed and I thought thing was fine. They ended calling saying we need to talk. I said ok. I had order pizza for the girls. This person goes in the kitchen. nd ended up going back out the door. I called to see what was going on.They said they was moving out and the relationship was over. I begged and please with this person.They was not hearing me. So i let it go. They left.I stayed in the apartment until i found another. They found a place. So we kept seeing each other and  having sex. But i was always the the one asking. Sometime they would  say no,And make excuses. But i wouldnt give up. Me crying. Anyway they help me many differents ways.We still was acting we were together without the title. This ran into some trouble. They came to my rescue.etc.Going to concerts just having fun. But it was on and off. like sometimes when we get the arguing they tell me we shouldnt talk for a while. About a week will pass and they will call again. so many times that happen I can't cant. Any i bought some concert tickets for us to do for this person birthday. A month in a advance. Went and bought clothes and shoes.Just because we wasnt to together they did the same for me.So we got into a argument and they said they didnt want to go. So I got upset went to this person house knock on the door they told me that they had company and i started hitting and screaming. Just went crazy. Police came.So we didnt go to the concert.I felt so bad about it.I apologize over and over again. So we agreed that we need to leave each other alone.Because it was a emotional rollercoaster. But i couldnt. I wanted some closure and they wouldnt give it to me, So a week pass and still talked,but at each other not to each other.So this person goes out to a club. Where my aunt worked at and seen her walk in with someone. So my aunt called me and told me. So the following sunday was this person birthday i went out. Met a friend at there. And walk in this person. They walk right pass me as if i wasnt there, We stayed there. So they left first and i left and I called. Ended up going to this person house. We talk. Very dry.So I left.Weeks later they ened up telling that they like this person my aunt seen them with.So I said i was happy for them.They poke and poke until they got the emotion they wanted for me. Telling how they treat them etc.So this pass Christmas they said they had gifts for the girls. At first i was going to accept them. I talked to me uncle he tld me not to. So i called got the voicemail. So I left a nice message.They text and say "WHAT U WANT'. so i text and told them not to bring the gifts that they were happy. And i couldnt stand to see them come here on christmas day and leave to be with someone else.So they got so upset. Told me F me.Then came new year eve and i emailed this long emailed on how i love them enough to let them go and i no they want to be happy,To start the New year. I didnt  think they was going to reply. So i hear a ring at the door. Open the door the gifts was by the door. I didnt call cause i had company. So i emailed back and said the girls said thank u.So the next day she emailed me and said that she wanted to talk to the girls. So i let them.They came over and talk to the girls. I let them have there time.So she left and i called. We talked on the phone for 5 hours. I played like i wasnt still in love anymore. I emailed them the next 2days saying i was still in love but im going to try to let go.Caused they was in a relationship.So for the pass month this been coming to my house and seeing the girls. The last time they came by we played poker and talked.We lotion each other feet. I said I dont think there girlfriend will like this. And they got uncomfortable and left.So i called and told them they shouldnt come back over anymore. They hesitated and ask why. I said cause they have someone and they had a problem with my ex being around.Why do it to them. And I didnt want the Karma. So they got off the phone. The next day i got a email saying they told there girlfriend they been seeing me and they didnt have a issue with it.And they thought about what i said and i was right.And they going to leave the issue alone.I this last for 7months.Nothing but Drama.
