Thanks for the reply Raghnar. I was thinking along the same lines when I was contemplating what to do about the whole situation. Maybe it was just a one off thing, let it go and maybe I'd find something really special on the other side. Situations like this in relationships almost feel like a coin toss, you just hope calling heads is the right choice. I feel pretty good about my decision though and I'll live with it.
Congrats on the four years together by the way. It really doesn't sound like a long time, but when you've been through a long string of bad relationships it makes you think how special it is to wade through all the muck and mire of dating and come out on the other side with somebody you truly love and care about. Its pretty darn cool if you ask me.
