Okay I'm in high school I was talking with this guy and he seemed like he really liked me but I didn't want him to think I was totally crazy about him so I made him chase me a little. Kind of like hard to get. We have been acquaintances for awhile and we started flirting and then talking for probably a few weeks then we went on christmas vac and things were different. He just stopped talking to me stopped looking at me everything? Why? Please don't be to hash but be honest, thanks.

You guys took things TOO slow in my perspective and a vacation is long enough to erase all the contact you guys had. You should let him know you like him more than of an acquaintance.

Maybe he got tired of the cat and mouse game. Many reasons come to mind but only he knows the real reason to your question. So maybe you should ask him. Best of luck!

He is the only one who knows,all else would be guessing.
I suggest you ask him.
