Follow your bliss bro! If your feelin it, go do it. Decide and dont turn back. It will work out somehow, it always does
I'm going through a break up as well.. go for it man, it will help you get over this girl. And I agree with mothman, if she got presented the situation she would most likely go for it. I've got two weeks until I move and leave my girl, then I will be on the search for some to help me get over my relationship.. fucking break ups fucking suck, heart torn in half type of deal.. oh well, thats life.
I think he means that women who dump a good guy mostly do it because another guy with more money came along. I personally have not found this to be true that often.
