Breaking up always sucks, but just hang in there. Remember that you are still a complete and healthy person even on your own. Long term relationships get so tangled in breakups because you've been with this one person with whom you've shared everything for a long time, and it's tough sometimes to separate who you are at your core from the person you've become with her.Squilookle said:snip
The healing process takes time, often several months, before you can even think of talking to that person again without picking the emotional scab. I know it's tough, but it's for the good of both of you. (also, don't get stuck in a rebound)
If you can manage it, be rational, calm, and understanding. Remember, she's been with you and only you since she was 18 or so, and she might need some time to get her own bearings on herself, her direction in life, and to figure out who she is.
Teenage years are when we figure out our identity and that sort of stuff mentioned above, so if you've spend your entire adult life planning around one person it's easy to lose track of who you are.
Try not to blame her, try not to grovel and beg, and most importantly, don't blame yourself. It doesn't sound like there's anything you can do to change her mind, and if there were, it might not be fair to her.
Your life isn't ending, you're just starting a new chapter. It's still your story.
