We're both 16.
Ok so last December we started chatting on FB. Then after 5 days, he just ignored me all of a sudden. In those 5 days he was the one who is always starting the conversation. Then January came and he starts chatting to me again. :| and after a week, ignores me. Is he playing hard to get or something? If so, then what should I do?
Oh and I caught him looking at me several times. When I was laughing or talking to my friends.
Does he like me? Should I make the first move?
I also like him by the way. Haha
He likes to joke around people. Everyone in our class likes him.
Oh and one time when we were chatting, I asked him if he wanted to be my gayfriend(jokingly of course) then he said no I want to be your boyfriend (idk if he was serious when he said this) and he said that line several times in our chat.
Recently, I was really grateful at what he did and I said love you! Then he printscreened it and posted it on FB. :|
I don't really know why he did that. Is he making fun of me?

Well from what I see he has not matured to the point of handling a relationship. Facebook is not a serious means of communicating and should really not be used as a medium for deep feelings. I'm sure thi are other things he does that annoys you but honestly and I hate to sound like a parent as my mom told me this when I was your age... at 16 have fun because you have your whole life to date.. and this was true. I looked back at my high school years and added up the amount of money I could have saved buy I spent in my "relationship. It was madness, and at the end I had nothing to show for it except a broken heart. So think about the relationship thing a little before stressing about your crush.

Love is nothing to play with

Oh OK thanks for the advice :) well actually after 3 days of chatting on FB he asked me what my number is so yea.. haha! :)

Any time love I wish you luck! And remember stay true to who you are...
