Best way to get back at an Ex Girlfriend

I wanna get back at my ex girlfriend any suggestions?

there is none ur just wasting ur time on her.. get a new one

You can try to fuck her, like in old times. Leld.

But in case, i did it two times in my life and both was successful

There is lots of ways you could do this, just common sense is needed.

Just get a new one pal, new is always better, as once Barney Stinson said.

1: Get a new one 2: go to his house when there aren't his parents and with an excuse and rape the shit out of her XD

Why? It's like an "ex car". You know it's broken! Get a new one!

Get a fresher one like a 13 years old one like we all do

Get over her, and find someone who will treat you better
It will kill her to see you happy with someone else.

Let her go. Get a fresh one. Fresh one's are better then used one's. Always!
