Wait and stay or girl move on: need advice

Okay so I'm 18 (will be 19 in april) and he just turned 20 two weeks ago.

So in december this guy had followed me on insta then added my snap and begun to snap me. At first I wasnt too interested and would answer sometimes. Then at the end of december I started to answer more frequently and he seemed nice, although he was a bit cocky as he would say how girls come up to him usually and he got hired on the spot for a job because of his looks. I kinda brushed that off cuz he didnt seem to say it too seriously and was never like oh I'm so good looking, and yes he is good looking although hes not even my usual "type". So in the beginning of January, he asked to hang out and go for a car ride and I said yes. It went really well he was fun to be with and there was a lot of chemistry and we literally just drove around and talked. Then he asked to hang out the next day which we did and he bought me a drink from tim hortons lol. Then a few days later we hung out again at his house and I gave him hand and he fingered me. Then again we hung out and I gave head and got fingered, but he wanted to have sex but I said no and he kinda insisted again then I said no and he said okay thats fine sorry. Also, he had told me that I gave him the best hand and head hes ever got and tbh not to be cocky or something I think I am good at head as I've been told and I used to watch vids on how to do it rlly good lmao, but he never came and said hes only ever came from sex, but told me he was so close when I gave him head. But during these hangouts, it would always be at night time and he would be like we need to actually hang out during the day and I said yes we do. Later I had asked him to do something during the day and he said he couldnt cuz he was too busy with school work. Then one night we were talking and somehow we got on the topic of being gay and I told him how I am an accepting person and I believe love is love, while he said he believes love is for a woman and man only, that was a huge turn off for me. But I did like him so I thought maybe I can change his views or something. We hung out again after and went to the mall and it was a nice time. Then recently, well the last Friday in January, we hung out and had sex but it was not good as we did it in his moms house while everyone was sleeping and it was so hard to be quiet as his bed is noisy and we heard someone walking around, so we decided to stop. Then the next day he went to the bar and was drunk and asked if I could pick him up and take him home which I did and he threw up like 5 times during the ride. Ever since then, he has barely spoke to me and he told me he has been busy with school because of exams so I just kinda was like okay cuz I get it school comes first. But honestly I think it's not that hard to say hey what's up or something like once in awhile. Like we havent talked for over a week and I see his snap score go up, usually not by a lot but it does go up. He has told me hes not an affectionate person as he wasnt raised in an affectionate home like he doesnt even say I love you to his dad. The last time we talked I asked if he likes me and he said yeah so idk. But like I said he hasn't spoken to me since as he said he has to study for exams. I dont know if I should wait until he messages me, if he ever does or maybe he used me for sex. Idk what to do. What should I do?

Lol sorry if it's long or if I seem dramatic.
