Age has less to do with it and being human has everything to do with it. True, usually at a younger age, because of insecurities, but it could happen to anyone, especially if you find someone you click so well with. That is so rare and something we all want in a potential date, or even friendship. It could happen to anyone, regardless of age. However, I have noticed that as I get older, experience teaches me how to respond and deal with such actions in a more assertive manner. But that come with time as you date more people. That's why I agree with Adam228. The quickest and easiest way to get over someone is to get back out there and meet other people. I wouldn't put so much emphasis on relationships or serious.dating right now. Trust me you will have plenty of time in your 30's and older for that. Just date casually, make new new friends, meet new people, make new social connections. Those new connections will teach you how to deal with tough situations like, "I can't get over him". Trust me, my friend. There are so many people out there to meet, so many things to do, learn, and see, and experience. That's where your energy should be. And the social connections you make now could turn into something more serious later. You never know what the future holds for you. Keep it open, bud.
