In love with a most likely straight guy

I am 18, started college just 2 weeks ago in a small town in Mexico. I came out to my mother a little over a week ago (I realized I was gay since I was 14) and she is surprisingly really supportive. Starting June, the University I go to hosted this event were you could meet the other people that were getting in. I met this guy, let's call him Anthony, and we got along really well. I am the kind of person that can imagine a whole future of friendship even if I just met a person, so it isn't the first time that this kind of stuff has happened to me. We were together for almost all the event and I found it really nice that he looked for me multiple times when we separated. He liked me too, apparently. One week later I get his number and chat with him during the day. We got to know the basic things about each other, sent memes, etc. We could definitely talk and get along nicely. I've never had any romantic relationship with anyone, for obvious reasons, but it is something I look forward to with a guy, especially someone like him. We saw each other three times during the summer (cuz he went out of town for around a month) but we did chat a lot. This only got me more interested and anxious to see him. I do realize he never gave me any concrete reasons for me to believe he is gay, only the ones I noticed (he had never been in a relationship, the way he talked to me), which I should've had taken with an even smaller particle of salt. I was hooked (I still am), and set him as a goal for when school started. Three days before the first day of college and there is this introductory event, my first time seeing him after a month and a half. I greet him normally (neither of us are really expressive) but had a great time together the whole day. I really believed something could happen between us. We have various classes together and we sit near each other when possible, work together and such. We truly have friendship potential, but I want more. Unfortunately, he may not be gay (I can't really complain about this, how could I fall for a guy I was not sure about his sexuality?). There is this girl that likes Anthony (she explicitely told him), I do not know what he responded, though. When they can be together (they do not share any classes at all) they hug, touch with their legs, etc. It gets me jealous. She looks for him most of the time, the main reason I was skeptical about him liking her. Also, she had a boyfriend and now broke up with him to be with Anthony (things weren't going well, anyway). Anthony does not want a relationship right away but told me he will eventually ( he asks me for advice ha ha). So know I'm on gay limbo, kinda obssesed with this guy and it hurts that I may never be able to have him. I like him so much. Now that I'm out to my mother I can tell her this stuff but i still cant get him out of my head. I feel unmotivated because he was the only thing that got me through the day (a very toxic way of thinking, but it has always been like that for me. I used to look forward to videogames and now people). I just want to tell others, I wish I could be completely out but it is hard where I live. It is a small town, everyone talks about everybody. My mom says I should wait until I talk with a specialist, I agree. However, I have so many repressed feelings and emotions I havent gotten out yet; this is not my first crush. I am supposed to be 100% focused on school and this is an obstacle. Even if he were gay I wouldn't know what to do, probably just hook up and act like real lovers in the shadows, the most unhealthy type of relationship. I do not even know what I want. The only thing I truly believe is that I need to get rid of this ASAP, but don't know how to... Thanks
