I have a good friend who was with her man from when she was 16 and he was 22. He was arsey, aggressive, and rude to most of her family and friends, and everyone but her could see he was horrible. He controlled everything she did, told her how to dress, made sure she stayed under 9 stone, and size 8 or less, and mocked and belittled her regularly. It was horrible to witness.
In addition, he hated everything about Christmas, and refused to have a single Christmas decoration in the house, and no tree (obviously.) She loved Christmas but didn't even dare mention it, let alone have it in the house. Also, he was scared of flying, so they never went abroad on holiday, and just went to North Wales. HIS wishes trumped HERS every single time.
They were together for 6 years, and when she was 22 and he was 28, they got married. The wedding cost £20,000, the honeymoon cost £5000 (and this was on top of the wedding.)
It lasted 6 months. All that time wasted with this horrid man, and £25,000 too! At least she got out when she was only in her mid 20's, but yeah, that's the shortest marriage I have ever known with people I know.
Personally, I think it takes a lot of courage to get up and walk away from a marriage, especially after many years, and when you have kids, and financial commitments and intertwined families...
I know several women who stayed in dull and loveless (though not necessarily abusive) marriages, because they had big financial commitments and children together, and they said they planned on leaving when the kids left uni. One woman I know says she left it and left it, and by the time she and her DH had no financial commitments and no kids at home, it was too late.
She was mid 50's, fat, and past it, (her words!) and too old to retrain for a new career, or to get a new man. (Not that she wanted one anyway.) SHE said she regretted staying, and is now with a fat miserable old man of nearly 60, who moans every minute of every day, who never lifts a finger in the house, and who she hates more every day. I know several women at this stage, and they say they just wish he would die.
So if it is possible to get out when you're younger, then do. Don't live a life of regret, like many do...........
