OF COURSE you can game her again- when you game your ex- girfriend and it works you´ll feel an incredible moment of gain a victory cause your mission was harder that in the beginning..
I reckon you should game any woman, tease laugh and have fun with any woman who cross your path regardless of who it is. Don't change who you are, or who you want to be.
to be fair i had every intention of marryin her... just lifes circumstances got in the way... i suppose i just want to end it on a high so later at some point we could go again
