Financial talk

I think I'm in love with my guy friend, but he's gay so he doesn't like me back. We used to be roommates and good friends, but we became toxic / jerks to each other so I moved away for a 'break.' I've been with my parents for 6 months, going to school, working and saving money. I plan to return to live with my roommate this summer. But I still check his facebook 5 times a day, I still wish he would call me (which he never does), I still remember all the mean things he said to me and they are affecting my self-esteem. I DO NOT want him to 'go straight' for me, I just want to get over him, get along with him and be respected by him. Can anyone offer any advice or pertinent questions / comments? Thanks for your help. PS - moving out is not an option right now. He's the only person I have to live with in the city, and we scored an excellent deal on a rental house.
