Even though you guys say it's a waste, I'm not saying it wasn't by any means, but aren't you glad you did it though??
I mean, you know where you went wrong or you now know the signs to watch for with the next one. This way you can bolt when it gets to that point if need be. I use my past relationships as a tool for watching out for the future guys to be had. Sometimes the nice looking ones don't tend to be so nice, but sometimes they do. That's a win/lose right there.
