Where do I stand with this guy?

[Kool]

Theres this guy. We met last summer when he inboxed me on facebook telling me how I was VERY pretty, and now we text alot. I am two years younger than him. When we text, we are always flirting. He always tells me i'm very pretty. My name is Martina and he gave me the nick name mar mar. And I also have a nickname for him. Everytime he sees me, he tells me that I look good. He got his phone taken up, and he mentioned me on twitter saying that he misses messing with me. And on my birthday he was like "Happy Birthday" I said thanks, and he was like "You're welcome " Yep, he added a winky face. But the problem is...everyone knows that he wouldnt be more than friends with someone younger than him, and he has nicknames for a lot of girls, so idk where I stand. What do you think?
