I am trying to get back into the game to start talking to women again but I can't forget the last girl I was with :/

I've had women try to talk with me but I was generally disinterested and can't bring myself to have the drive to talk to women again. I talked to more women when I was with this girl than after she broke up with me..

Any tips / ideas?

It's just emotional trauma. You can and will fully recover from this, and when you do which will be soon if you play your cards right, you will of learned more about yourself. And as a result, have better inner game.

You have to realize that there is going to be a stupid amount of girls out there that are even better than your ex. You have to stop doubting the female abundance, and realize it's real. Ask yourself, why are you wasting time on this girl that's already gone, when there are girls even more amazing out there, there are so many in fact that you couldn't fuck them all in this life time even if you wanted to. This is exciting shit, get excited! Think about how good the path ahead is going to be.
