BIL is my best friend. We have known each other for more than a decade and he is the reason his brother and I met. We go out together at least once a fortnight, for a meal or to the cinema etc, which IME are normal activities for best friends.
But for some reason, all I need to say to people is the above and I get the
face.
I should mention that BIL and I were 'involved' a very long time ago, but it wasn't serious, was just a few isolated incidents and DP knows all about it (it was many years before we got together). I don't tell people this as a matter of course, so they only have my first paragraph to go on, information wise. DP is a lecturer, and sometimes works quite late, BIL often comes round and has dinner with me without DP being there. To see people's reaction to this, you'd think I'd told them I was shagging him over the dining room table!
Is it really that strange that BIL and I are that close? As I said, he is the reason DP and I are together to begin with. I'm just tired of being given the face every time this comes up.
I think it's normal/nice. AIBU?
