Hey, what's up everyone. You all know the story.

Me & her have been together for ~2 years. I found out about a 'friend' she was talking to, I told her it's either me or him and she blocked him. And today I got into her laptop and saw that she didn't really block him, they merely changed platforms so they could talk behind my back.

I just called her and confronted her, she did get scared shitless and all that. I did plan on breaking up with her, but seeing how incredibly scared she was, and also because she kept repeating how she'll do "anything to get back together" I thought: Is it possible to keep her around for a while as a slave to mentally abuse? I told her to wake her parents up in the middle of the night to tell them what she did and she did it, so we're off to a great start. I was never really buff and am relatively young (23) to have a high enough SMV for women to act like slaves around me like that naturally, but I can't remember when I felt happier than when I was in this much in control of her. How long can this 'relationship' where she'll do anything for me last? Any tips on how to keep the fire burning?
