Confusing man!

So.. I'm kinda getting back out there after separating from my husband 8 months ago. (Abusive relationship) and I am now with a man from time to time and I really like him.. And I have told him I liked him, and also explained when we got together I wasn't expecting a relationship or anything.. But...

During sex, sometimes he asks me "do you want to have my baby".. Or.. " will you marry me" or "are you ready to be my girlfriend".. And I kind of choke and say yes.. Thinking it's what he wants to hear.. But I kind of feel like a booty call most of the time.

I have 2 kids (he's never met and they know nothing about him) and that kind of freaks him out a little.. He has admitted this. He won't come to my apartment, even on weekends the house is empty..

Anyways.. Just looking for advice..
