I just finalized my divorce in April. The in-between time when I knew I was getting a divorce to when it is actually finalized was the most stressful time in my life. I'm a tall thin guy and I lost 20 lbs throughout that time and truthfully, my ex and I got along pretty well!
Sorry about you getting out of the hobby, but at least it's only temporary.
Keep your head up, try not to internalize the issue and realize that some people are just not meant to be together. Also, don't rush out and try to find someone new just to be with someone. You'll know when the time is right. Good luck and keep your head up!
