I don’t recognise the text in the first paragraph. Here’s what the French text in the second paragraph says. It’s rather intimate and personal, so I’ve put in a spoiler box:
Very interesting! I really want to sleep with you too. It would suit me tomorrow for sure. Are you coming here tomorrow?
Your girlfriend sent you a message in Russian and French which seems to be a follow-on conversation that you had being having with her, but in what language?
Don’t know. An ex sometimes sent me messages in spanish (a third language for both of us) for no other reason than the fact she likes using this language…
