DP calls me his little cum-bucket. I didn't mind at first because I didn't realise what it meant (I thought he was saying come-bucket although I realise that doesn't make sense) but he's saying it outside of the home too which is even worse. I saw him writing a text to his mate who we're going out with at the weekend and he refered to me as "cb". He denies it was short for cum-bucket but refused to say what else it could mean!
AIBU?? It makes me cringe.
