One of my best friends is a divorce lawyer.
He says that most men have no clue whatsoever that there is a problem, until the papers are served on them. In many cases, those papers come with a restraining order, forcing him to move out THAT DAY.
When the woman decides it's over, all she has to do, is claim fear of abuse, and he is outta there, and there is NOTHING he can do about it. The police will remove him, if he doesnt go willingly, and she is free to move anyone else into his home that same day.
A man can go to work one day, and be on the streets that same night, with one word from his wife against him to the courts. Married men are sitting ducks.
