One day I sat next to that new 15 year old guy in my class, and that's when it all started...
We got to know each other and exchanged phone numbers. He even gave me a DVD to watch at home! When we finished school and got home, I texted him first and we stayed texting each other for 3 days: Friday, Saturday, and Sunday. And most of the time he was the one to text first and to tell me good morning, sweet dreams...

Then when we returned to school on Monday, we kept making eye contact and smiling at each other for a few days... Until he suddenly stopped texting me and making eye contact with me the next week.

But tonight, he texted me for the first time in so long saying that he doesn't want me making eye contact with him anymore and that he doesn't like me and thinks of me as a stranger.
At first he was trying to flirt with me and get my attention, but now I'm very confused. Not sure if he's just playing hard to get, or he's over me... Please help and give me advice! Thanks!

Guys can be cruel and it is probably nothing you did at all. You cannot make someone like you. Let him have his way and see if he comes back. If not, move on. If he does, great. But don't lose any sleep over this one because it just isn't worth it.
