So.. a while back, I was texting a guy (I thought he knew it was me) and it was going really good. He told me that he liked me and thought I was a cool person. 20 text messages later, he finds out that it wasn't who he thought was texting him. I now have to see him in class. But, I don't want it to be weird between us. What should I do?

Text him, and see if this makes a difference, now he knows who he is texting.

If he thought you were someone else, be careful, because obviously he texts others beside you.

Go right up to him in class. Smile and say "wasn't that weird?" Laugh and go to your desk. Treat him like a friend 'cause he is one now, whether you're the girl he said he liked or not.

It won't be weird if you don't let it be. If he wants more conversation he can text you, or talk to you in the hall.

Perfect way to handle it. Brush it off and laugh with him about it.. . It won't be weird after that :)

I agree, its best to make a joke out of it instead of having things be socially akward between you two
