Name changed for this as it's sensitive.
My parents live in another country, on a recent visit to them I spent a day doing errand type things accompanied by a local man, I don't speak the language well enough, we went out afterwards with parents and had a few beers. It was late and I went outside to smoke, he followed and grabbed my face and tried to shove his tongue down my throat, I put a stop to it immediately and said not a chance and that I'm happily married, he knows my husband, well.
Since I returned I've had a text asking if I'm ok and if I arrived home. I can't think of how to reply, it needs to be firm and yet polite, I don't want to make waves just put him further into his place. Can anyone advise?
Further note he is ten+ years older than me.
