What Girls Said 1
I'm confused on the last 3 sentences here. I would tell you that if you do date other people it will help you get over the ex. If she is young and immature move on and just chalk it up to growing pains!

It sounds like you don't exactly know what you want. On the other hand as you said the girl did a number on you, so getting a few dating site accounts isn't embarrassing at all. But on the other hand you genuinely care for the girl, so looking at the dating sites seems pointless, I mean, before you even consider dating any other girls, you really should get you head in order. If you really care for the girl then either get rid of those feelings and move on or try and get the relationship running again. Your choice, but having feelings for a girl while you are trying the dating game isn't smart and could quite likely bite you and the girl you might end up trying to date and that won't be fun for anyone.
