Long distance relationship... help!?

I think he might unless he thinks it's him you are talking about and he doesn't know how to let you down easy. Unless you said to him that you have no one else then I don't think it's the latter. If he responds at all you just have to analyze what it could mean. If he asks a lot about this "boy" then he could feel jealous. You shouldn't make assumptions just in case they are wrong, I have soo done that before. If you feel he does like you or at least he would understand I believe you should. It may be hard to do but if he's not giving you a straight answer you might never know. Is he the type to go after those he likes? I hope my input helped. Good luck!!
