re: I need some honest relationship advice

Is that how this works, one OTer 'quits' to tag in a 'retired' one?

OP, you hate to hear this, but you are the back up/fall to guy. I promise that pussys seen other dick than yours. ESPECIALLY if its been LD. Like others have suggested, the best idea is to get out. BUT, may I suggest, you play the game too. Keep the nonsense talk up with her while dating other chicks. Its only fair, think of it as playing by her rules. Win, win.
