Mine is very complicated. His family never liked me. They think I caused split between him and his ex. They have a daughter together and the sisters are using the child to come between us. They used to call around 11:00pm/12:00 midnight and say the child misses him and I put a stop to it. His child came to visit us once and got bruised from a bicycle while playing with my kids and we were in big trouble for that. His sisters and ex called, insulting us for hurting the child and I decided that the child should not come to my house anymore, instead he should go to his parents’ house and he will visit her there.

I do not comment when he talks about his family or child anymore because he does not see that they are using the child to break our relationship and for that he thinks that I hate his child. We have been together for 9 years now and (1) I have never been to his family home (2) he has never taken our child to his parents’ home. His excuse is his sisters do not want my child so he's scared that they will poison her, blah blah blah. He's in serious debts or so he says and I pay for everything in the house.

Lately I have found out that he's socializing with more than 100 women on social network, when I confronted him he agreed to making a "mistake" because he's not technology person, he "thought that he was just making friends" when I ask him to delete them, he tells me that he will do it in his own time.

Should I stay in this relationship?

That depends on what you want from life for you and your child. If you want the drama, lying, no family contact, etc, etc, etc, then stay in the relationship. If you want something better then make the decision to leave. It sounds like you know the answer to this question already.

I wish you luck.

You've been dealing with this mess for nine years? How old is his child and how old is your? Sounds like you are getting tired of it. I know I would be.

Here's what I'm reading in OP's own words: "“They used to call around 11:00pm/12:00 midnight and say the child misses him & i put a stop to it ... and i decided that the child should not come to my house anymore, ... and for that he thinks that i hate his child ... i pay for everything in the house ... he's socialising with more than 100 women on social network ... when i confronted him”

I see a myriad of problems, some involving the child, most of them involving a controlling woman. I see a lot of directives which she issues and a mention that she financially supports the household.

"OP" put a stop to this or that, OP "decided" this or that? "Confrontation" about this or that? I see no input on the part of the boyfriend. He does, however, seem to obey very well - right up until the social media sites.

I think the relationship is doomed, and I also don't think it's about the child.

Counselling? Certainly.
