Is he gay or bi and does he like me?

DUDE this is like my story repeated again. It happened to me that I met this cute guy when we were 16 and 17, one day he broke up with his girlfriend and went to my house while I was on my laptop he said he was leaving so I said: Later I cant stand cuz I have a bonner from watching porn he so he laughed and went to watch what I was playing on my laptop then he grabbed me and we start having sex. Next week he went back with her ex, I felt bad and told him but all he said 'I AM NOT GAY' so I stopped talking to him, we were really close friends so one day he came up to me accusing me of leaving him behind after promising to be there for him no matter what. ( be realistic I told him that cuz I loved him) so I explained to him the feelings I had, he just did not answer anything and started grabbing me and there we go to bed again. Next day I texted him telling him about last nite and he said that we should never do that again. Too late I was so into him. I cried for months, I failed classes, I quit my job, I went to therapy. Here I am happy been single having fun with friends, he is fine with his girlfriend and a daughter and when he gets drunk he calls me and txt me saying that he misses me. If I was given the chance to do it all over again. I would have never touched him back and I would have tell him I was gay as soon as I could, believe me you still will find many good people in your life.
