After 5 years working my program, I can tell you it will get better if you stick with yours.
The intense 14 years we had together seem like it happened to somebody else.
Do I still miss him? Sometimes.
If I happen to run into him, it is easy with no emotional punch. That doesn't mean I don't care, I am successfully able to resist the urge to jump in and fix.
As for the rest of the world, I am REALLY picky who I hang out with.
