Sory to hear that bro.
My bestman faced the same situation, when he got a surprize day off from his time in air force, he went home and saw two pairs of sneakers outside his house (the fucking bitch was having a threesome)
He caught her on tape and send the tape at her parents just to see her litle slut.
Not to say that the fuckers had a real good time after they done, we were waiting for them outside the room with baseball sticks.
It was a nice game.
Nevertheless bad things like that make you stronger.
DONT LET ONE BITCH GET YOU DOWN NO MATER THE GOOD TIMES SPENT WITH HER, THERE WILL BE BETTER.
