Hey Vulc...keep your chin up. Go for a drive, put on *your* favorite tunes -- nothing that reminds you of her -- and let it blast! Just be safe....
And, a sage word of advice: as you said there were irrepairable differences, so there's room to grow there. Whether it was your fault, her fault, or both (it's not my place to ask or to know), there's room there for you to improve yourself. This is one of life's little lessons...don't miss it. Because what you learn now will help you when the next girl comes along.
Trust me...my wife and I are very happy together, but I'm not perfect (and neither is she) so as we "gracefully grow old together" we learn more about ourselves and each other. There are still things about myself that I need to improve and learn to live with -- and I'm 32! You're only done learning when you stop living.
So think about what happened, and WHY, and learn from it. In that way you can take something positive from this.
