Never divorced, but my first one (mother of our 4 kids) decided she'd rather snort up Peru than raise kids, told me I should take the kids, so I took 'em and left. Raised them by myself, rarely ever hearing from her. Kids were old enough to know what was what and were glad we left. I never filed for divorce--didn't believe in it. She died from drug use/abuse about 20 years later when she came down with cancer and the drug use had destroyed her liver and she couldn't handle the chemo.
Got another one now--been in happy bliss since 1995. She can't cook, loathes cows, hates farm work--I don't care.
