I didn't read the other comments.
I think you are doing the right thing. I made the same choice not very long ago myself.
I've had one best friend since first grade and the other since 6th. When I moved to be with my bf. I tried to keep in touch with them. After awhile one friend got a bf and stopped talking to me. I moved back closer and she would make and cancel plans to be with her bf. I gave up on trying. And stop talking to her. I kept talking to the other friend and most conversations and nights out she b*tched bout the other. She also won't allow my bf around and was just not mature at all. My bf has to kids and I grew up fast. I couldn't handle the high school drama.
I don't talk to either now and I feel better for it. I'm sad we grew apart but it happens.
I'm not sure what my point was there. Just had to share.
I told her I had plans.. I didn't want to back out on my boyfriend again(I've been sick for the last week, so had to cancel twice). It's just frustrating that I always have to be the one to make the effort. Plus friend A's boyfriend is always there, and I've never said anything about it. I know she really likes him, so I treat him as I would a friend. It's not like this is a girl's night, it's a party with both sexes present. And my boyfriend isn't new, he's been around for a year(been dating for a year). They both know of him, and they know how I feel. Yet she has no consideration for my feelings? I just don't get her.
I agree with teko, if you have been friends for that long I would not end a friendship over this. Just tell her you have plans but do not cut her out of your life permanently. I hope things work out with your BF but what if they don't? Is it worth loosing a life long friendship over?
It wasn't intimate though.. there were people invited that she's known for maybe a month. I've put in all the effort to keep our friendship and always call, text, facebook, etc to stay in touch. I don't get that effort from her. She is ALWAYS busy, supposedly, and just doesn't make the time for me. I've gotten so tired of being the one who keeps us together. I drive down there, they never drive to see me. It has gotten so frustrating to me. Friendship is a 2 way street, and to me, it feels like it's all on my side for effort.
Maybe friend A just wanted to keep the surprise party amongst close friends and family? I mean it seems innocent enuff to want to take the bf and all, but if everyone coming was doing that then it would cease to be the intimate party she planned and you cannot say okay to one and no so someone else. Also would it be possible that friend A might feel like you have put them on the backburner so to speak since meeting this guy? You have been friends for a long time, and I would not give up on them so easily. You could have attended the party for an hour or so and then gotten together with you bf later as well. Maybe your friend feels like they dont rank with you anymore? And maybe feeling a little left out themselves?
