No problem, I am sure you'll do fine, and I don't blame you for the way you feel as it has only been 3 days and that's within the grieving period. My last break up broke my heart enough to the point where like, the next day I was already looking ahead, because it was such a betrayal all I could do is go forth. I think that really helped me. Don't hate her or anything, but see at as enough of a breach so as the only way from here is forward. You did the right thing too, trying to preserve the relationship, you upheld your end of the bargain, so to speak, so you did what you could. In the future you will find the woman who really deserves the kind of commitment you can bring to a relationship.
