I know nobody can tell me what to do, or what I should do. But any advice would be helpful!

The father of my twins left me 2 weeks ago. & I'm now a day away from being 36 weeks. He hasn't been very supportive at all. When I try to talk to him, text him, call him.. he just puts me down putting all the blame on me. He wants to be there for the birth, & he agrees to come home for a week or so after they are born to help. These are his first kids, I have a 5 year old. But he says he doesn't want to miss anything. I keep thinking to myself, "where are you now then?" You know? Things are so hard right now. Just going to the grocery store is a challenge. We split up because "we argue to much." But have you took onto consideration I'm baring 2 children right now, of course I'm stress, and confused, scared, and depressed now. I guess my question is, how would you ladies handle it? Would you let him be at the birth, and be home for a week? Or would you want to be stubborn like me and say f**k you?
