If I were u I'd avoid any drunken conversations and magically start needing to pee if he was sober and started to rave and excuse yourself to the bathroom.
At the same time people are entitled to express themselves. I know my sponsor told me her partner raves sometimes and she just doesn't respond except to say 'a ha' 'mmm' and 'is that right?' Said it actually stops him as he eventually wears himself out.
We can't stop another persons behaviour but we can change our own to minimise the effects on ourselves.
Learnt that in al anon. I use to think I should just put up with whatever someone else dished out but not these days it hurts a bit too much for my liking.
I am known to rave myself a bit these days too. I'd love to say I am aware this affect has on others but that is not true every day. Never thought I'd admit that about myself as I tend to be self righteous at times but alas it is true.
