DH's nearly 21 old sister is going to be coming to stay, for 12 weeks initially. This is because we live closer to her university placement, which she is about to return to after being with her mum for lock down.
I'm happy for her to come, she's a lovely girl and DD absolutely adores her! I am a bit nervous though, mostly because she is very shy and anxious. This means that she (and none of her 3 siblings!) are ever comfortable enough to say what they want or help themselves to anything, which means I or DH ironically end up waiting on them hand and foot. It has historically pissed me off, for example when she and her siblings have been around and I've spent a long time cooking and they won't offer to wash up. DH laughs it off and then cleans up.
It's going to increase our food costs and I will probably end up resenting cooking every night for an adult who can help out but won't. DH will do it but I'm a better cook!
She also has no friends, really and will rely on us for company. Even during lock down I guess I would expect someone of her age to be in their room some of the time, chatting to friends etc. I think I'm dreading feeling like a stranger in my own home and having no alone time with DH.
DH is aware of all of this and says that he will speak to her before she comes, but I'm really worried about it. Particularly the selfish stuff like wanting DH to myself!
Any tips for how to make it work without me coming off as a bitch?
