Dude,

I'd say you messed up pretty good. Regardless of what you may think, she has every right to be pissed and to dump you right on your cheating head, or ass, as the case may be.

I won't offer any advice, but I will say if the outcome is negative for you, it's because you deserve it.

Not hatin' you, just calling it like it is - the bottom line is you cheated on her.

Best,

JP
