Virginity Feels

I lost my virginity a while ago to my friend. I never thought of him romantically before that but now I do and he never thought of me like that. He tells me he has feelings for me now but I can't help but think that he only has feelings for me because we took each other's virginities. I'm so confused and don't want to get anymore emotionally involved if he only likes me for the sex. I really don't know what to do. I am talk to him about it because he will just call me crazy but idk...
