does he like me???

so i have been best friends with a guy for the past 3 years. we know each other really well and are super comfortable around each other-- like change in front of each other and it not be weird or awkward. we've always been kind of flirty towards each other but lately hes been texting me and face timing me a lot more and always says he misses me and stuff even though i see him kind of regularly. we are going to prom together and he always tells me how excited he is. last week he also asked my friend if she thought it would be weird if we hooked up (i wouldn't mind it, i'm super comfortable around him so i'd rather lose my virginity to him than someone i don't know well). what do you guys think?? does he like me or is he just trying to fuck or just want to be friends??
