Apparently he upset a previous girlfriend by some of his comments and not sure if he patted her on the bum in passing or something. But he is very rude and says sexual things. The family just seem to let it go.
For example. At the dinner table. Family gathered- often says "oh Knickers' (not that bad). To me and young 20s niece "Oh you're having an orgasm over that!" (we looked at each other mortified).
Last weekend, was bad, I was commenting on a local farm doing chicken golding sessions for people with dementia and he said something about "preferring pussy stroking sessions".
It's just grim. In fact he often turns things round to sexual innuendo. I feel sorry for MIl...but no-one says anything!
AIBU to put up with this without saying anything...but what would you say?
