Personally, playing this game reminded me of times I was cheated on; I got so angry I nearly smashed my computer. Just standing there while someone else was with my girlfriend... The game isn't bad, though—you should give it a try.
Dude, you dodged a bullet, at least you weren't married to that slut and then take half the money you earned your whole life or had kids with her that wont be yours and still have to F pay child support. If you do somehow get married, have the girl sign up a prenup that also states that paternity test are mandatory. If she has no plans to cheat, she will sign them up.
