my emotions are so confused this sucks... please help!!!

I was recently in a long distance relationship and have since left him but if I tell this story I might as well tell it from the beginning... when I was dating A (my ex from Nebraska) I was trying to make a bad relationship work again... then I ran into an old fuck buddy, let's call him T... we became close friends and still had chemistry but neither of us acted on it because we were both in long distance relationships with people in Nebraska while we are in California. T and I decided we were just going to be friends but because we both missed going out with someone in person us hanging out became more like dates with every passing day... one night there was a birthday party we were helping host for his roommate and I was basically cooking with him all night until he had to go operate the mechanical bull... which left me cooking all alone. I knew he needed help and was actually having fun helping him. By the end of the night some drama went down and he got really upset... I pulled him into a hug to calm him down and then we both caught each other's eyes and fell into a deep passionate kiss... I'm sure you can figure out how our night ended. The next morning we woke up still holding each other and we knew we couldn't hide how we felt anymore. I was already wanting to end things with A because I knew I could never be the monogamous housewife and mother he was looking for. But I knew T still had his girl(R) in Nebraska so I didn't want to seem desperate for a taken man so I tried to talk and figure stuff out with A. It was past repairing because we didn't want the same things so I ended it. That still left T with R. She is nice but she's not who I see T with... she's too monogamous for him but he has 3 ex wives and 4 kids between ages 4-17. So I am trying not to fall too hard for him yet. He accidentally called me his girlfriend and I told him he can ask when he doesn't already have a girlfriend to which he pouted... I feel that when he goes to see her soon he should end it but that's his relationship so I'm staying out of it just like he stayed out of mine... for now we still act like a couple and he likes spoiling me and taking me out wherever I want.. But I know we aren't a real couple... he texts and calls her every day and I know I shouldn't be jealous because I'm the one with him. But when I hear him tell her that he loves her it hurts me because I want to get to a point he says that to me. But we are taking it slow which I feel just means he doesn't want to break up with her yet but he still wants me too so idk if I'm crazy and just going to get hurt or if I give him time he will want me more than the girl he has the history with... any advice?
