“I don’t want you to know how I feel”

So in about February/March of last year, I joined Tinder looking for fwb not too long after a breakup and there is this one guy in particular that still has me confused. Basically, I caught feelings for him and I realized that, at the time, I couldn’t have another relationship w feelings in the moment bc my last relationship had ruined me. So instead of doing what a grown up would do, I was, I admit, immature and backed out of hooking up, I think once or twice. Eventually, he stopped trying to set it up and stopped talking to me. A couple months later, we talked as friends but it seemed he was interested, only for us to stop talking again for a little bit. Nothing happened, we just faded. Well we started talking again in December and this time it’s confusing. He seems to go really back and forth: sometimes he’ll show interest, others he’ll seem detached. I figured I was coming on too strong, as I do sometimes, so I just let it be and left him alone for a little bit. Well the last couple nights he went back to seeming interested and it was okay until tonight. He got drunk so we were talking and I told him that I was confused about him and he said that I was confusing and that he felt I would go back and forth w it. He also told me he didn’t show how he feels bc he doesn’t want me to know how he feels. I don’t get it...
