Try to follow this one. It's a real-life soap opera, and the end result is great as far as I'm concerned.
I was with my ex girlfriend for a few years during college. We broke it off because she decided she wanted to cheat on me with her ex boyfriend. Her ex was with another girl at the time, so she actually stole him away from her. Needless to say, on my side of things I was pretty hurt and we didn't speak for several years.
I moved to Virginia and after a few years we got back in touch somehow. I invited her down for a week to hang out and see if we could remain friends after all we had been through. At the time I was living with my (female) cousin who had never met the ex. I was a little worried about how they would get along because they're very different personalities, or so I thought. They actually hit it off very well, talking about angels, holistic healing, Oprah, and a bunch of other bullshit I could care less about. When the ex left at the end of the week they exchanged numbers and email addresses.
A few months later my cousin went to visit my ex, who lived with a boyfriend of several years. I thought that was a little strange since they had only met once before. As time went on, the trips to visit her became more frequent, and I thought "great, I guess they turned out to be good friends".
One day my ex called me and was terribly upset. (Here's where the story gets a little crazy, and if you ask me, funny). My cousin's trips to visit my ex (and my ex's boyfriend) had often resulted in threesomes. My ex, her boyfriend, and my cousin. It really disgusted me. Well it turned out that my ex's boyfriend had grown interested in my cousin instead of my ex. He broke it off with my ex and now my ex and my cousin hated each other. And you're calling to cry to me about this because why?
I couldn't help but laugh my ass off and tell my ex that karma is a bitch. She stole someone else's boyfriend years earlier and ruined our relationship, and now she wants me to feel sorry that it's happened to her? I don't think so. Now that's what I call justice.
