<human>: Condense the text into a few key points

Recently I've been hanging out more with a guy I'm interested in. We've made out a few times, and slept over at each others places, with nothing going farther than a make-out sesh. After the 3rd time spending the night with each other, he texted me saying that he didn't want to lead my one, he likes hanging out with me but doesn't want to see anyone exclusively. I was/am okay with this but I also thought this would mean we would still be hanging out/being physical which I really enjoyed. I asked him over to hook up one night and he said he had other plans, not bothersome in itself, but then I found out he slept with his ex that night. Then the next day we were hanging out and he wouldn't talk to me at all. And now he's being kind of flirty again. Now I've found out that last year he did something remarkably similar with another girl (hang out, make out, no relationship, sleep with ex, don't talk to other girl, but then get really flirty again). I don't know how to confront him about what's actually going on with us, or if my confusion with the situation is unfounded, or if I'm just being ridiculous and can't handle being around guys. Advice would be greatly appreciated.
<bot>: Dude I'm into is also into me but doesn't want a relationship, still flirts with me nonstop, slept with his ex, makes out with me, wont talk to me about what we want from each other.
