My partners brother (bil) is, IMO, a d**k. He's 27, arrogant and rude (especially to his own family). He's regarded as a real ladies man and is popular, and to his parents he's the golden boy who can do no wrong. They never pull him up on his disrespectful behaviour, so in reality it's no wonder he's the way he is.
We had a baby a few months ago, the first on both sides, and he was to come stay this weekend to spend time with us.
In reality it turns out he used our house as a base for a date. He was away all day Saturday with some mystery girl, and when he returned late afternoon he (as usual) had nothing to tell us, or ask us, and instead blanked us and played with the baby. We went out for dinner (which tbh he paid for) but he literally had nothing to say to us during the meal, and after trying several ways to drag conversation out of him we gave up. It started to feel like an interrogation since our questions only got one word answers!
AIBU to stop him staying with us anymore? I come from a family that loves to share stories and have a laugh together, so I can't get my head around him having so little interest that he can't even hold a conversation with us. My partner takes the opinion that his brother is just shy, which if he wasn't so arrogant I might possibly believe! His mum has mentioned before that she worries he's depressed, so it wouldn't go down well if we said he couldn't come over, but I just feel like it's turning a blind eye to his behaviour by letting him stay even though he's rude (IMO).
