My situation.

My situation? Ok I had a LO from previous, I met my for this we'll say SO we flirted had sex found out I was pregnant and things went tits up cuz he wasn't looking a relationship. We didn't speak for almost a year and a half. He came back into mine and our LOs life yet his family still doesn't know :/ but that's a whole other issue lol. I'm dealing with that. Well we started sleeping together and As far as I was concerned we were just sex buddies, well I got drunk and slept with someone else. I was very honest and told him and we argued like mad where he hinted that he had fell in love with me. We have sorted things out but now he's saying that if we are sleeping together it's exclusive. Does this mean I am his girlfriend?
