My GF is in love with me but she is back with her ex (her daughter father) because she is afraid of him. We had a long distance relationship so I couldn't be there to help her all the time. I asked her to move with me but she had to finish her school first and she was afraid of losing the custody of her daughter.

The father of her daughter is a manipulative, psycho guy. He harassed her all the time with the excuse of their daughter.
She has a follower personality and doesn’t have the balls to take action. Now after 8 months of relation with me she is back with him. She admitted that she doesn’t love him and that she loves me.

Her mother knows that and she support me but the rest of the family think that she has to be with him even thought she doesn’t love him because she was married with him and she has a daughter with him. That love is not important and that the most important is the convenience of their daughter. Now is trying to be with him. She is trying to fight against her feelings and trying to cut the lines of communication with me.

I know that she is not happy (she is trying to show a different face) and I know that that relation is not going to work because she is there only because is convenient for her.

I would gladly appreciate your feedbacks.

Doesn't matter what she tells you, if she is married to a buffoon then its her that has to take action, and you to get out of her business until she does. That means absolutely leave her alone!!

Seems to me like you did everything that could have been done, but it wasn't enough. If she's back with him, doesn't matter who's will, then that's too bad. I would say move on buddy, because she sounds like an easily manipulated and dependent human being. You don't need that. If she's going to let herself get sucked back into a relationship with her ex husband and father of her child so be it.

The ball's in her court, and if she ain't doing anything about it, then why would you try and keep playing.
