confused crush

Ok so I like this guy and he's rlly funny and sweet he's not like any guy I've ever met he's open we are both in 7th grade I totally don't want anything serious but I want him to be my first kiss he does not know I like him I just want some advice he's rlly a nice guy I've never had a bf but I would not be against being closer with him any suggestions I kinda want to send him a candy gram lol they hand them out on Valentine's Day I don't wanna be forward but whenever I'm around him I feel giggle and bubbly he makes me smile and I think he might like me to btw I am 13 but I'm rlly self conscious I don't like my body. You see I was on meds that made me gain a lot of weight. I have OCD and I was in hospitals all last year I don't want him or anyone else to think I'm weird. He doesn't know I have OCD I'm very good at hiding it and it's a lot better with my meds. I just want some advice I'm gunna tell my gammy tonite that I like him I tell her everything but my mama is pushy lol and try's to learn anything she can but I just want something plz comment anything ok bye
