Thanks for everyone's opinions. I do appreciate it.
The reason she doesn't want him in the child's life is because he is a dead beat dad who is not willing to support his boy. She says she would rather go without the child support than have him around.
You are right, and I have told her before looks aren't everything as she has told me when we started to date that is all she has. She realises she is a very dificult person to be with but in her messed up brain she always find's a reason not to find help.
I have now stepped back and the ball is in her court so it's out of my hands.
To be honest, I knew deep down the chances of this relationship lasting was about zero. I just thought I could make it work somehow, or at least get her some help for her boy's sake.
