So I go to camp once a summer for a week and this was my last year (I'm 17) most of our counselors are from other countries and all above 18 and I was fooling around (not in "that" way) with one of the guy counselors who according to him is only a few years older than me and we just threw acorns at each other all week, splashed each other in the lake and pulled pranks on each other's cabins. Once I got home he friended me on Facebook and ever since we've been chatting nearly every day on Facebook messenger (about 2+ weeks) and at camp, every counselor goes by a nickname so that campers don't look them up on Facebook but this one looked me up and let me know his real name. He even told me his birthday and I sent him a birthday gift because he requested friendship bracelets. What does this mean?
