What's the solution to my friend's problem ?

There's no nice way about it. She always has relied on him and for whatever reason they broke up she still think he will be there. Try counceling for the kids sake. He also has to remember even if he doesnt like the little boy, he's still his son's brother. so he doesnt have a choice on that. She needs to become more independant and counceling might help her. He cant always give in but he needs to help her out. Suport him in either way, but dont give him **** about it. Its hard enought on him in the first place.
