I’m there with you. Only about 15 years younger, and still (4 years post divorce) without a 2nd wife. 20 years of marriage, 4 kids, stoic and idealistic determination to keep the “marriage” alive.
Disaster. Absolute disaster.
Sorry to hear it. It was absolutely the worst thing I ever had to deal with. It does get better. Hang in there. This can be terribly destructive to a man. Support structures are there for women. In most cases, you’ll go it alone, very alone.
It does get better. You have my every good wish for a bright future, which will come.
Hang in there bud.
