I started seeing someone new about six weeks ago. I've known him for several years. His coffee invitation came out of the blue. had never considered him in a romantic way but and I have always got on very well so I gave it a chance. He is lovely and we are having a really nice time together. He admitted last night he has liked me for years. But I'm not sure if we are a proper 'thing' yet. At what point did you know or have a chat about being exclusive etc?
