i met his work colleagues last week for the first time, (we've been together for nearly 5 years) and they kept saying how much he talks about me and how smitten he is - which is nice but i can't help but think they were kinda going over the top and it made me not believe them?

Our relationship is totally stable and pretty perfect but its funny as i didn't see him as being that sort of guy who talks about me, but they knew loads about me. They were nice girls (women) some married or with guys. They were asking me to go out with them on their girls nights and everything, which was nice i think maybe it just sacre me as it was so, well surprising!
