I don't understand why you're waiting for him to leave you? You sound miserable. Leave him!

When my ex-fiance left me I did exactly what you're doing. I tried to hang on, I tried to bring him back to me, I tried ignoring him and moving on with my life, I tried fixing myself up so he would see I didn't need him. Nothing worked. I knew he was going to leave me. I knew he was done with the relationship. I just didn't want to be the one who ended it. I wasted an entire summer waiting for him to dump me. Looking back now I don't see the point.

You have a friend offering you a place to stay. Take it. Start packing. Let him see you're packing. Give him an address of where you'll be in case he wants to see the baby. Let him know you're done. If he wants to keep you, he'll fight for you. If he doesn't fight for you, you're better off leaving.
