Need advice for possible gay friend

This post is going to be very longSo there's this guy I've been friends with for 3 years now and me and my friends think is gay. The only problem is that I only get to see him for a week once a year at a Christian camp, where being gay is seen as a sin.Anyways him and I were really close the entire week and the reason I've been wondering whether or not he's gay is because of how he started treating me towards the end of camp and how he acted in general. When I grew up I acted very flamboyant and almost everyone in my school knew I was gay before I did and he acts just like me.Also near the end of camp he kept taking pictures of himself on my phone (96 selfies) and he started giving me hugs. Like for 2 minutes at a time before breakfast he would just hug me. I think people know I'm gay there even though I'm still in the closet. As I said earlier people would always ask me if I was gay and knew I was gay. And one day he just sat on my lap without his shirt on and used my phone and watched people playing card games. The shirtless part isn't really important but imo it's not something anyone else there would do.And he always hung out with girls at camp like I used to. Not flirty but more of just being friends with them.The major thing that confused me was right before he left he told me he loved me twice. And I know a lot of people say stuff like I love you bro in a non romantic way but it seemed different.I feel like I'm reading too much into this because I really really like him and I really want him to be gay. He's the main reason I haven't told my parents I don't want to be Christian because then I couldn't go to camp and see him and any of my friends there.What should I do? Should I leave it be and just try and stay friends with him or what
