I'm currently living with my best friend who is 26, and has just started a new job in retail. She was having casual sex with a guy but stopped after a few weeks. At the time he had a long term girlfriend though he says he's aboit to break up with her. He smokes weed daily and regularly takes coke, and possibly other substances. He has a very low income in a job with no possibilities, and evidently has very little respect for women. My housemate upon finding out she was pregnant decided to keep it from him as she didn't want him in her life, but as always things get out and he now knows, and wants to be involved and to quote him "play happy families" with her. When she first found out, she asked if I would help her, getting a bigger flat together (I earn a decent wage) and to raise the child together as her family aren't supportive. However the father doesn't want me to have any involvement as he "doesn't think I like him" which is correct, but I have always been nice to him, just (I think understandably) I wouldn't want a adulterer and person that does hard drugs (the Coke) around my children should I have any. I want the best for my friend and her child, so am wondering what I'm supposed to do in this situation, as he wants me out of the picture, thus causing friction and possibly creating a toxic environment for the child once she/he is here. My friend wants to belive him, and says that she'd rather lose him than me, but he's the father of her child, so obviously I could never allow that choice to have to be made, I jist want the best for them, only haven't a clue what that is...
