If you two are talking, you already have a good start. Do you know if he is married or if he's seeing somebody? If so, you can move on. Most important, talk to him and tell him how you feel. Don't keep anything else to your self, it may be the wrong thing!

Have you tried finding somebody around your age, maybe even a close guy friend can get your mind off of things. I'm not saying that all older men will take advantage of young women but "most" will. They will seem nice but it's all probably an act to get with you. Be careful, you are still young and probably can't "read" men to well right now.
