How can I handle this fight with my girlfriend the best way ?

[sn_laughs]

you can just block her. or leave it be. unless she's got pictures of you with whores.
it doesn't matter if you live your life normally and she does all that on facebook. shes gonna make herself look like an upset whore.

and you can joke about it on fb, saying, hey I know you miss me, thanks for your service the other day. but honestly, I'll pay you some other time, u get to charge me interest. and I'm sorry if I hurt you a lil bit more that night, must be a little "pushy" after drinking. You know, alcohol.....
But hey, these things on my wall, they've got to stop. but I gotta admit its pretty nice of a decoration. I'll change my mind. just keep posting.
And see how she goes about it.

If shes got no proof about you. just let her keep talking. its not gonna wrekc your life anyway. u can block her if u want anyway.
Cheers,
God bless.
