background - normal* evening just getting into bed with boyfriend*
Me: tell me about when** you were younger
We both lived aboard (in separate countries) growing up* and tells fun stories of what he got up to - I'm easily* pleased 
Him: no I'm* too tired you tell me about when you were in Berlin (*I lived there for two years before uni)
Me: sorry* I'm afraid those stories are off limits tonight it's* your turn!
Him: whispers behind me slut 
He says that's what I was insinuating and has stormed off in a huff because I don't want him all over me straight after he said that.
Even if I had been 'insinuating' which I wasn't I don't think it's ever appropriate to call your GF a slut?? He knows my history, and to say it's whilst we were in bed. I'm not FUMING just a bit put out and confused.
Aibu or is he?
