Warning: this is an advice question...

I know what you mean, question and act like the same friend as last year. Take things slow, like act like nothing is wrong and gradually get to the point of asking why he is never paying any attention to you. All guys are different, some ignore when they love you, some ignore when they hate you, some never realize that they ignore you, and some have something wrong in their lives and they just want to be distant from everyone else. I have experience with all of this. The key is time and patience, my dear.

This is hard to answer. But I guess, maybe, since it's been a while and he's avoiding you, ask why he is doing this? maybe you did something wrong and you don't realize it? go and see him, then question him why he's doing this. Guys can be so stubborn and it's a pain cause we, unfortunately can't read their minds. It is strange for a guy who's just a friend to just automatically ignore you. I hope it all works out for you and that you get a straight answer from him.

Ummm....boys change alot, not sure if they change more the girls, but they do. It's up to you, to text him something else.

Well trying texting him one more time if he doesn't answer back then you know whats going on.

My friend moved a couple of years ago and I got his phone number to keep in touch, but every time I say 'hey, he doesn't respond. I took the hint and haven't texted the dude since. If he doesn't know you, take the hint.
