guy probs help

ok girls I need your help of course...ok so there is this guy he's 17 soon to be 18 (he's a junior) and I'm 18 soon to be 19 (I'm a senior) we fucked over the summer once but he didn't want to push/force me into a relationship I wasn't ready for you might say why did we fuck then well we basically fucked because I knew my boyfriend was cheating on me and I just didn't want to believe it was true. I have had feelings for this guy forever now and I really like him. He is currently SINGLE and so am I!!! but here's the bad news...we were going to have plans but he ended up going to one of his parents houses unexpectedly because of a divorce and I totally understand. He told me I'm perfect (yesterday he told me that) but today we didn't talk. I saw him at school we don't talk at school because we don't like people knowing our personal business but girls he's absolutely pretty pretty perfect. He's what every girl dreams of. I get butterflies in my stomach just thinking about him if I hear his name I instantly blush and smile I think about him constantly if we don't talk for some time like we stopped talking for about 4 months and just started again it's like time never stopped. He knows I like him it's no secret but I'm ready for him to be mine I wanted to asked I prom last year but I wasn't allowed to attend due to family issues and I am pretty sure he know that I was planning on asking him but I want to go this year to my senior prom with him. I don't fantasize to much about this relationship because I don't want to be disappointed but how do I keep him interested like he's definitely interested but it's just complicated. If you guys pray please add me in your prayers I really need some happiness in my life right now.
