I have similar problems as a guy. Ill meet someone, date them for about 3-6 months and then have a breakup. Ive had about 6 girlfriends but I never seem to be able to get any type of commitment out of it. 4 out of the 6 girlfriends wanted something longer but I broke it off. My friends say I just havent found "the right girl" for me yet, and that maybe so. Sometimes I feel like I flirt with girls im not even that interested in. Immaturity I guess, but im going to uni next year so I hope it will change and I think I am ready to really be selective next time.
