My sisters second husband is behaving like a lodger. Married for 10 years, she has 2 children late teens. He hasn’t changed his post from his home, she doesn’t know how much he earns, he spends every hour he doesn’t work down on the farm (not a big farm, and they don’t live on it)and every Saturday evening having food with his Mum? He isn’t even on the mortgage, never went to any of the kids sporting fixtures, I could go on. . After a row he moved home (yes back to mum!) and hasn’t been in contact, 2 weeks ago! Surely this isn’t normal behavior of a married man? What should she do?
