Idk what I'm doing

I had a very long conversation with a FWB type guy. told him I care about him more than a friend and I pretty much want him. he decided to give his ex a chance. we didn't talk for about a week or so and we've decided to try to stay friends. since then he has been texting me more and we hungout the other night, and stupidly slept together again. I didn't think this would happen again and I just don't know what to do with myself anymore!
