Relationship advice. So I live with my baby's father, & have been for the past 3 months. But the whole year we've been seeing each other, he's been on and off with his sons mother. Basically we've been on and off as well. Well, he's recently been arrested, and I've been doing everything. Literally. The money on his books, and phone. Answering phone calls all time of the day and night. Keeping his family updated, as well as baby mama. And finding AND paying for his lawyer...but he recently told her that he was going to marry her at the end of this. Then ONCE AGAIN flipped it, and came running back to me. Idk what to do anymore. Sorry this is so long.
