My case? Yes, ONLY my case:
Got married when barely 20 (too young, yes). Had job I loved, she hated (night job, 11-7). I said, "Why don't you get something in daytime to occupy your time and help A LITTLE". She: "No can do".
Went away for couple years. She hated that. "Maybe get a p/t job to help out in the meantime?" "No can do".
Started a cleaning business. Yep, you guessed it...at night. She hated it. "You wanna help me?" "No can do".
Started driving truck, eventually heavy equipment. AHH...DAYS!!! Yes, but 12 or more-hour days and always 6, sometimes 7 days a week. She hated that. Made tons o money during summer but laid off in winter. She spent it all. "Uh, maybe you can get a small job to help out during winter?" "No can do."
Started UPS. AHHH...DAYS again. No. LONG days. No good. THEN, started feeders. You know what THAT means. Yes, back to nights. I was happy. She, of course HATED it.
All this time, I was getting more attention "outside" the home. My fault? Of course! I LET myself get more attention.
Cut to the chase: I left, after (I think) 27 years. Never been happier. Got a wife (of 11 yrs) that's a working machine. If not at her job, then here. Never sits down. Doesn't complain about a thing.
After paying off all the exes debts (in the decree) we now live debt free.
In short, was it my fault? Well, yes. I accept some blame. But I think I always provided. She never had to worry about anything...except the next thing to complain about. I remember one time I came home. She was bawling hysterically. Me: "WTF is your problem THIS TIME?" Well, what I ACTUALLY said was, "What's the matter, dear?" She: "I have to have this VERY, VERY, VERY, VERY, VERY serious operation. I could DIE!". Me: "If only you would!". Well, what I actually said was, "Really, what is it, dear?" She: "I have to have my Gall Bladder out!". Biting my tongue to keep from laughing, I queried, "What did the DR say?" She: "Well, I haven't been to a DR but I just KNOW that's what it is". That's been about 35 yrs ago and to this day...she still has her Gall Bladder.
She always accused me of going to leave her for somebody younger. She married (what a fool!) a store clerk, 15 years her junior. Go figger.
He has to wheel her around in a chair. Why? Nothing. She's just morbidly obese now (I mean, MORBIDLY), and FINALLY has a disease she can be proud of: DIABETES, which, in her case, is debilitating. They've declared bankruptcy once and are close to living in a shelter now. "So, how's that bitching about night work going NOW!"
So, again, was it MY fault? I look at it like this:
Yes, I DID get married for an eternity. And, by golly, I LIVED an eternity with her. Were my vows sacred? Well, at the time but I guess I lied. Plain and simple, I lied. Did SHE lived up to her vows? Just by what I said here today, do you think so?
Chastise me all you want for what I did or think but if I had to stay there, I STILL wouldn't be THERE. I'd be in prison right now.
What UPS the cause of this? Hmpf! By itself, NO. Was UPS a contributing factor? Yes, But, like I said, I'd probably be in prison now for doing something far worse.
