There are many random ways that you can get even with an ex girlfriend that cheated on you. I can think of about 5 really good ways off the top of my head. Here are the ways:
1) Go out on a date with her friend.
2) Tell her parents all the bad things she has done.
3) Pop her tires and key her car.
4) Tell her that you cheated to and you don’t give a shit!
5) Submit naked pictures and videos of her having sex to get revenge on her!
I for one think that submitting nude sex videos of her is the best way ever to get your true revenge! Just like this nasty exgf here!
