to not want BiL & his girlfriend to stay?

[MichelleRooJnr]

I don't like BiL's gf.
We don't get on, have nothing in common and I find her rude and unpleasant.
We've never had an argument or anything but she just rubs me up the wrong way.

So BiL has texted DP today to say "when are free in Feb - we'll come up for a night out".

I've asked DP to make arrangements to just see his brother but he says IABU - that they want to come and stay and we should just bear it for a night.

But I really don't want to.
AIBU?

Is this your long term partner - ie future husband? If yes, you need to consider the long term nature of your relationship. The woman you don't like could marry your partner's brother, she could have his children etc.

Would you risk rocking the boat that much just for 1 night?

I assume it is also your partners house? If so, you dont get to dictate whether his relatives can stay in the spare room. You can choose to go out with your friends, have a night way on the same pretext, refuse to cook for them etc. But you cannot isolate your DP from his brother on the grounds you don;t like them.

if its your house, different matter.

YABU

You will never get to know and like her if you don't give her a chance.

She could be your sister-in-law in time

But you never know, with luck she feels the same and be washing her hair that night.

Yes my long term partner of 14yrs (no wedding on the horizon )
BiL's gf of 1 yr.
I know it's important for DP to spend time with his brother but she and I are worlds apart.
I am and will be pleasant when I see her at 'occasions' like DP's dad's 70th a few weeks ago when she perched on the sofa with her coat on for half an hour before saying she was off home to watch celeb BB!

DP finds spending time with her a struggle too.
Dp and I are boring.
When we go out we go to 'old man pubs' whereas she is very glam and obviously bored so we take them to bars.
Conversation is a struggle.
They have been to stay for 'a night out' about 5 or 6 times already and it's just an awkward faff.
It's really hard to not come across as a miserable old cow - but actually we have tried hard and just find her such hard work.

Welcome them over but say that as bars are so expensive and boring these days you will cook supper and have a nice chat/catchup. I'll bet she won't come. If she does you can bugger off to bed and leave them to it. Easy.
