If you really love her then stay faithful... It sounds like you really get on with each other and have built up a good relationship. It sounds like you don't really know this other girl that well and are considering her based on appearance alone... she might turn out to be super annoying or dumb or whatever... just realise if you are gonna try going for her then it's gonna be taking a chance - you already know what u have with your current girl.
Anyway, good luck with whatever u decide. |
