I have a auntie who left her husband whom try to bite his arm off and then laid his hands on his wife

She went to live with her mother far a few days and she told her straight away don't be so f****** stupid

And she went back to her husband the same day

For some contacts he did lose his own father which was affecting his mental health

That you can see how easy it can be to just leave somebody if there is no marriage

Also from my own experience I have dated a woman for six months and then she ghosted me for another month without telling me

What was happening so I had no idea if she was alive or dead
