I'm a woman and if someone threatened me and threatened me, my home, my children they would be in some serious doo doo. Before no fault divorce lack of sex was grounds for divorce- on both sides. That is not really arguable. I don't know why society has become accepting of this as if it's ok.
If that he were my husband doing that to me he would no longer have a job, by any means necessary, money or a house if not a few broken bones and I'm only slightly facetious. That's vicious. He needs a vicious divorce lawyer.
No way should any human being put up with that.
