Is my ex bf using me or does he really care

He told me a week or so ago that he was looking for a gf and can't fu*k with me anymore.. I wished him the best with that and said bye. Days later he says he wants to come over and I said why and he said he doesn't know. We've tried planning it but he's always busy or working.. So I haven't seen him since the break up. We're also dirty on snap chat.. which that tells me he's still sexually attracted to me. He says he wants to have sex with me. We do talk about other stuff not just sex. But when I ask if he likes me he says he doesn't know what he feels. My ex and I have been broken up for a little over a month now. October came and I wanted to hang out and go to the county fair with him. I asked him to come. But he didn't come. He still cares, because he gets bothered when I hang with other guys. He just wont tell me how he feels. Whenever I mention getting back with him he ignores my msgs. What should I do? Just let him be and have him talk to me first? Or do the no contact thing?


As of right now, we haven't talked. I told him how he changed and that I'll stop and go. Its a matter of if he texts me first or if I later give in a talk.
What should I do?
