Is this BAD Son's wife is 26 weeks pregnant with #4 I can't even be Excited Am I wrong?

This girl has been an Omen every since he et her 14 years ago. She was 15 then and he was 16. She suckered him into getting her pregnant by lying to him. She was on the pill and her 26 year old sister gave them Rubbers. They have a 13 year old son from that it was a nightmare then and still is. One reason after another she and her sister have been Hell bent on destroying his life. Her older sister would buy him Alcohol in exchange for Sex. He quit school at 18 and they moved in together and just one thing after another. They also have a 9 year old and a 7 year old. Now they moved her older sister in with them who is 33 and refuses to work. She has a 8 year old and 14 year old my son and his wife also support they struggle every week having to Borrow money and our Vehicle constantly. I got a phone call last week that my son was working late and his wife was having extreme abdominal pains. I figured Gallbladder or Appendix. But NO she up and floors me she is 25 weeks pregnant. She only has 14 weeks to go. So now my Dumb *** Husband has up and asked them all 8 plus new baby to move in here. I am SO PI******. It is not funny. Our son his wife and 3.5 kids is one thing but why do I have to take in her Lazy Sister and her 2 disrespectful Kids. I hate the Hole Idea. But I was informed it is his house After All I am disabled. And he supports me so I have NO say so.
