My ex ended our marriage nearly 3 years ago, after over 25 years together.
He changed from a loving, caring husband and father, to one who has taken us to court twice in the last six months, we're back again for the Final Hearing next month. He's hidden assets, refusing to declare his pension etc, please get all the evidence of everything before you do anything.
Somehow i did in the early weeks before he moved out, but hes sold vehicles and denied it. Hes on five times my salary, now lives with someone on almost as high a salary as him, but is still trying to deny his earnings, refusing to provide proof less then a month before the Full Hearing.
Meanwhile, hes taken me to court to try and stop paying maintenance. Doesn't seem to enter his head, it would have been so much cheaper to pay maintenance rather then thousands of pounds to solicitors.
Have a totally different life now, i never would have chosen to be a single parent, but we're getting there, i've done new things, made new friends, am doing things i never would have if i'd still been married. So you can turn life around, still have bad times, but having good times too, went back to uni last year, will qualify in 18 months or so, still working part-time but just so busy. Doing volunteer work too, as i need the experience for my new job.
You'll get there too, you'll wonder why you didn't do something before, but please see a solicitor and find out your rights before you leave, it will make afterwards so much easier :)
