Of course you can, but having four ex girlfriends already (I'm not sure how old you are, if you're still pretty young and had four girlfriends already, that doesn't sound good) can really ruin your dating reputation. If people know you don't succeed in relationships, or you don't treat the girls right, or if you have a history of CHEATING or LYING in relationships (a HUGE minus), it'll be very hard for you to earn the trust of another girl. Good luck.
