Backstory: My parents are my Mum and (step) Dad who have been together since I was 4. DB is 2 years younger than me so always been in my life as much as I remember. He's always been so laid back he's horizontal with his mum throwing money at him and any problem she comes across rather than addressing issues.
A few years back he got involved in a group who were much older than him and went down the wrong path shall we say. He came to stay with us and my parents helped him sort his issues out. He was maybe 18 at the time.
He's now 26. Gone down the wrong path again. Wanted to get away from the town where he lives. His mother suggested he ask could he stay with my parents. My parents agreed, as they have always said to both of us, it's our home if ever we need it.
He's been there 6 weeks now. Sleeping on the sofa as they only have 1 bedroom. Contributed £40 in that time whilst they feed him and pay all the bills. My mum (so his step mum) has said he can stay as long as he wants. She said my step dad (his dad) surprisingly was extremely hard on him and bollocked him about the whole situation.
I know its none of my business, it's their house and upto them who stays but I'm not sure they arent being taken for a bit of a ride as there is no indication as to when he will be going home. His (ex?) gf is saving up for a deposit for a house in another town so I assume thats when he will be going. My parents dont have a lot of money, my mum and dad arent in the best of health and he seems to be walking all over them. Take for example when we went round at 11am the other day. He was still fast asleep on the sofa in the lounge, so we had to go in the kitchen/garden.
ARGH! I just dont want my parents being mugged off!
