DH and I were invited to my parents for dinner tonight along with our DD(6). Also invited were my sister and her husband along with their DD(5).
Everything was going well until an advert for DisneyLand Paris came on TV and DH very uncharacteristically spat "oh fuck off with your screeching kids, what a pile of shit."
DH never swears and certainly never talks like this at someone elses house. Everyone was pretty shocked, mum pulled cats bum face but nobody said anything, I just gave him "the look".
DD then said "but daddy, I'd like to go to DisneyWorld". DH then replies "yes, DisneyWORLD, there is a massive difference between Disneyland and disneyWORLD. DisneyLAND is in France and it's cheap and nasty, people only go there when they can't afford to go to America. If we do go, we'll be going to the REAL disneyworld in the USA."
dd squeals in delight. Sister looks at her hubby who shakes his head. DH see's this and adds "well come on, Disney Paris is a cheap cunt holiday!".
My mum at this point stands up and busies herself in the kitchen. I am furious. DH knows full well that my sister and her family are going to Paris next year. I ask to have a word in private and in the hallway I ask him what on earth he's playing at and why he's acting so odd. He says I'm over-reacting and he's just trying to liven up the evening. When we go back in DD is telling DN that she's sorry she won't be going to the REAL disneyworld as her parents are cheap. I tell her off and DH shouts "USA" to which DD copies and they both start shouting it. Mum comes back in and complains about the noise and my dad asks me how much DH has drank and suggests we take DD home. First time I've ever been asked to leave my parents house 
DH still refusing to apologise. AIBU to not let this one drop? he's totally shown me up in front of my family.
