Nothing at all against them, I mean I've only ever met them twice in nearly 3 years, but they seem nice. The man is a long-term friend of my partner's. They have offered us an open invitation to stay in their spare room for a couple of days.
Honestly I couldn't think of anything worse, it's nothing to do with them. But I'm terribly introverted and quiet and the thought of having to spend all that time with people I barely know makes me feel sick.
I don't really like staying at other people's houses (it's different when I stay at my family's as I can be myself) so generally I don't stay anywhere else apart from there or my partner's parents', I'd much rather get a hotel. I am so glad we don't have a spare room as I hate having people to stay too.
I probably sound really miserable but that's how I am.
Anyway aibu to decline this invitation? Not really sure what excuse I could give? don't want to lie, but what can I say except, I don't want to really?
Obviously my partner should still go by himself.
Maybe I could arrive in the evening late, sleep and leave early in the morning, but no more than that.
