Drowning in Pain

Honestly this doesn't even sound worth saving. He has checked out of the marriage and his relationship with his daughter, and doesn't even seem to care whether she has a roof over her head as long as he can excessively spend money (and ruin your credit while doing it) on what HE wants. Don't think your DD doesn't notice how dad has checked out of her life either, cause she does. You are basically supporting him and that's all he seems to care about anymore. And if he's out all nite like that and your not having sex, than I wouldn't doubt if he is sleeping around with other women too. He is not contributing anything emotionally or financially to the family, and honestly if I were you I would go see a lawyer.
