I was married to the same woman for 23 years until she walked out. I blamed myself initially but realized she had poisoned our friends against me, taking her side on things. I was an outcast with our friends, but instead of wallowing in pain, I did some soul searching to find out what happened in our marriage and how I was responsible for it for falling apart. I realized my mistakes, and I sleep better today than I did those first few months. I was a good husband, but my ex-wife wanted things her way or no way.
Once I realized it, I no longer felt the pain of the loss. I was just enjoying my newfound freedom and life. I even went back to school to earn a degree at my age.
