Three years ago, our son gave up working offshore because his wife was neglecting the children.
She threatened to take the house, kids, cars, bank accounts, and everything he'd ever own if he didn't start accommodating her "desire" by going back to working offshore so she could live "her own life without his interference".
Her girlfriend was going through a third divorce at the time and happily provided all kinds of layman's guidance and suggestions.
Result?
Son filed first. Obtained professional advice. Ended up with the house (that he had purchased prior to the marriage), custody of the children, child support, his car, a motorcycle, furnishings, and only had to give up half of a retirement plan.
She lives in a rent house, paycheck to paycheck, and has less than standard visitation.
Talk's cheap. Don't listen to anyone except an attorney - and even then get second opinions.
