8 year old step daughter issue

[JESSMARZUOLO]

I have an 8 year old step daughter who I have been in her life since she was about 5. When It is just me and her she acts pretty well we have a great time together. But she is very disrespectful to her father and now when her dad is around she is being very disrespectful to me. Yesterday she screamed in my face told me she don't have to listen to anything we say. I have a 6 year old son from past relationship and he would never disrespect an adult ever!! I don't know what to do anymore about it. Me and my husband are always bumping heads about it. He thinks its something mentally wrong with her but she i think she is a fine and it is just her being a brat because when your doing stuff she wants to do she is happy but when she doesn't want to do something or you have to discipline her it is like impossible. It is mostly a respect issue she has none for me or her dad. she knows what to say to both of us to really hurt our feelings.

Sounds like a Power play going on here,she is playing you both against each other, she is older now and feels she is able to do that. You and her Dad should be on the same page so she isnt getting mixed messages,is he trying to be the good guy in her eyes .He has to step in and give her Boundarys, there is no mental problem but if you are concerned about that always get her evaluated at The Docs.If it over small things you could let them go , back off a bit and not let it get into a confrontation, she will be a teen soon so nip it in the Bud now,see if you can moderate your expectations of her aswell.Can you guys do girls things together, so you can get closer take more of aninterest in her abd what she likes, you are the Adult it has to come from you.
