Younger Dsis, 29, lives with my parents. Her boyfriend, 27, lives with them too. Not that he was invited, she just gradually moved him in and now he virtually never leaves the house.
My parents are not keen on their relationship - he has not got a job and sits around playing computer games all day. Dsis works two jobs and is often out from 10am til 11pm leaving him in the house with parents. He does not go up to Dsis' room but hangs around downstairs sitting in my mum's place on the sofa all day (the best place for embroidery cos of the light!) or in the kitchen with my parents watching my mum cook and asking her about every ingredient that she puts in. ALL DAY. He never leaves the house except to go to the pub with mates. Even to the point of asking my dad to pick stuff up for him when he goes to the shops. Every meal is hoovered up by him, dad says it makes a huge difference to the food bill. If my dad asks what they're doing that evening, boyfriend will ask what's for dinner, and if he likes it, will stay in for it, he's quite open about it. They were there for the whole of Christmas and didn't even bring my dad a bottle of wine.
Parents are both retired so no escape at work for them. Dsis boyfriend is a know all and loves to lecture - butts in on every conversation with an "I know better" type comment.
This has been going on for a year. Despite having an MA, Dsis doesn't want to get a proper job (does bar jobs) because she wants to be free to travel. They both spent last year saving for a three month trip around Asia last autumn. This was at the expense of my parents. Dsis and him pay no rent and give no help around the house. Only time Dsis hoovered was when one of her other friends was coming to stay and that was only before she came, and only the room she was going to stay in - my mum cleaned up after, including stripping the bed etc. My parents were originally going to confront them about moving out when they got back from Asia, but then my mum didn't want to spoil Christmas for them. Now my dad is saying rents in London are too high, and not fair to kick them out.
Dsis is rude about how clean the house is - my parents are laid back housekeepers, but not filthy - but does not lift a finger to help. If asked she says she is too busy with work. She does find time for 30 mins on her exercise bike every morning, though.
If my parents say anything negative about the boyfriend Dsis goes APESHIT. Normally sweet, lovely girl but, if crossed, turns into a sweary maniac. It seems a bit bullying the way she holds this over them, so they are too scared to raise anything.
Parents v unhappy with situation. Continually complaining to me about how awful they are, yet unwilling to say anything. Literally every conversation I have with my mum is how awful it is living with the boyfriend, how rude he is, how she has no space for herself. She has started leaving the house just to get away from him.
FYI I live away from them with husband and DD, so this is not affecting me directly, just concerned for parents, I think, but feel free to correct me ;)
WIBU to have a word with Dsis or should I butt out?
