Several weeks ago DH invited a friend of his from out of the area to come and stay for a long weekend so that they could go together to some local rock-climbing and hiking events. These activities are something they both enjoy. I've met the friend briefly once before and he seems okay, but he was very quiet with me and noticeably more comfortable talking to other men. DH's set-up suited me: they'd be out for much of the day and I wasn't required to assume much of the social burden of entertaining.
Now, DH has been asked to attend a conference that will take place over two of the four days his friend is due to be here. DH doesn't actually need to go but wants to because of the professional contacts he'll be able to make. We've had a falling out because he's assumed that I'll be fine hosting his acquaintance on my own. He's all 'He'll be fine, he'll just go off every day and do his own thing. You'll barely notice he's here.'
Even if he does go out during the day, I'm going to have to spend evenings with him and I really don't want the pressure. Having someone here one-to-one is so much more intense than sharing the burden with DH.
DH has stomped off to bed accusing me of being unreasonable and saying that this guy has been looking forward to this weekend for months and that I'm ruining everything and that I'm getting incredibly unsociable. I think that's partly true: I'm getting older and I'm more fussy about who I put myself out for. We have great friends who are always a joy to see, but I don't think this man is ever going to be one of those. AIBU?
