Bf is living with his ex PlZ help

Could a man and woman who have history together be roommates and not have sex ever? Why would he keep it from his GF?

Im having a HARD time believing this and feel like I should reach out to the “ex gf”

My bf of 1.5 years has just revealed that hes been living with his ex gf before me for the last year.

I broke up with him of course and now I’m mourning my relationship but what he did was leave her place immediately and has been at his parents for 3 days since I found out. I am hurt and beyondddddddddd disgusted. What do I do?

He says they kissed a few times but aren’t sleeping together, I mean... we’re in out 30s who tf are u kidding.

Should I reach out to her. Something tells me I am the side chick. I’ve been with the man religiously or the last year n half... sometimes spending weekends... stays over my house, is around my family. Ive met his mother. He said his parents kicked him out a year ago and he couldn’t afford rent on his own and she opened her doors. But that’s what gets me.... u are a grown fucking man. And if it wasn’t a big deal. You would’ve told me.

He did ask me a year ago to get a place together and I said no... but why not tell me the reason to get a place was bcus u had nowhere to live? I have two small children under 10 and that’s why I said no.

I just don’t understand, I don’t understand why I always lose. My kids have two different dads bcus I am always left or cheated on. Could I be that bad?

I am shaking writing this. My heart is shattered we were talking marriage.
