Right, I think this is going to be a long one, so sorry in advance.
Two years ago there was a major falling out in our family, with the result that my dad, sister & I no longer have any contact with my brother. My mum is still in touch with him.
My parents live out of the country for most of the year, and we rent their UK house from them - cheaper rent for us, and they have a a place to stay when they come back here. In a few weeks time it's my mums birthday and she's throwing a big party at the house here. The subject of her inviting my brother came up a few times when she was last here, and I told her that whilst I don't really want him to come, it's her party, her house (ish!) and I would grit my teeth and put up with him being here. In the end, she said she thought it would be too awkward for everyone, and also that she doesn't entirely trust my dad not to say something after a few drinks.
Big relief all round.
Until tonight. I've just had an email from her about something else. Right at the end she says 'I´ll only be sixty once & I would like X to come to the party, but I don´t want you to feel awkward or uncomfortable. Tell me what you think'.
Now it is her party, and I don't want to say no. But....I would feel massively awkward, uncomfortable, angry with him for coming, and possibly resentful towards my mum for inviting him to 'my' house. But...it is her party. And this is her house. But... it's also my house, and I've told him in the past that he is not welcome at my house. But...I did tell her before that I would put up with it.
So. Would I BU to be honest with her and tell her that whilst I don't want him to come, I will put up with it (which sounds really martyred, I know)? Or say I just don't want him to come at all? Or do I just say, 'Your party, your guests'?
