I'm posting here for my sister. I have nc to protect her identity.
She has a useless dp and a couple of dc. She's works full time and he's unemployed but with some savings left over from his redundancy.
He goes and plays golf Monday-Friday from 9am until 2 with his friends then comes home and has a nap.
He goes to the pub every Thursday and Friday night. In the summer he will also go on a Saturday and Sunday with his friends and their gfs. Sister is never invited.
He then has other hobbies which he will randomly do on different days.
Then he demands sex on tap even if my sister doesn't want to. He gets angry if she declines the offer 
He does nothing in the house, not much with the kids. It's like the relationship revolves around his need to enjoy he life.
He refuses to get a job, refuses to do anything that he doesnt want to do.
He watches porn constantly too and now he's started going to the gym and injecting himself with steroids.
How do I help her without running the dickhead over?
