I've liked this guy for like 2 and a half years... but he goes to a different school. We have been texting for a long time and we almost met last summer but some things came up... after that we slowly quit talking and about a month ago my friend said I should talk to him again... but turns out he has a girlfriend now. I really really really like this guy :) I don't know what to do... im tired of waiting.

If he has a girlfriend, back off. Leave the relationship alone. Don't flirt and play games with him. It disrespects the other girl, and that could easily be you.

If you find you cannot just back off then the only other option is to be totally honest with him. Tell him, "I reached out because I was interested in going out with you. Since you have a girlfriend, it's a little awkward for me to know what to do. I don't want to disrespect either you or your girlfriend, but being friends and hearing about your new relationship is kind of hard, so I'm going to bow out." In doing this, you're telling him you're going to bow out of his life and let him alone with his girlfriend, but he knows the reason and if he wants to date you, well, he can make that decision.

Take care.
