I have been talking to this guy for almost 2 1/2 months. We have only hung out a few times. He doesn't want anything serious between us. Sometimes we don't have the time to hang out, and I think that lately he has been losing interest in me because I haven't been able to hang out in over a week. What can I do to let him know that I'm still interested in him?
yup.....get him alone and force yourself on him. If it's been 2-1/2 months he might be getting the wrong signal and think your NOT interested.
If he isn't into anything serious then that is guy talk for he just wants to bang you is all. So basically if you and him are not sleeping together or you aren't seeing him much he will probaly lose interest. What is it you are looking for with this boy anyway?
If he's losing interest, be the one to move on first. That'll either make him waaay more interested than ever before, OR it will just give you the chance to find someone else - whose interest will not waiver. Either way, you keep your dignity.
He has already told you that he doesn't want anything serious with you. If he was interested he would act like it and would've never said something like that. Move on.
