Girlfriend sent nude photo of herself to a guy on Facebook... and is still doing it!?

Look Hoss.... before you even wrote this question, you should have grabbed your balls and did what you feel is right. But since you didn't, let me break it down for you. First your girlfriend is a liar and she sneaks around while your not looking. Even tho there is no penetration involved, she is still sending naked pics to a random guy and talking about sex with him. Why the hell would you put up with that?? Either this is your first girlfriend and you have some bad puppy love or your stupid... and that's the bottom line!!! There is no third chance for this chick, leave her now and save yourself some heartache and keep that last bit of dignity that you have. ( thats if you have any left).
