About 2 years ago I had to relocated a long way from home for work and thus make a new circle of friends. I quickly became close friends with one of my colleagues (lets call her Pam) and we spent a lot of time socialising outside work (we became each others go to person for the cinema, pub lunches etc). About 6 months ago Pam became quite stressed for a number of reasons and didn't really want to socialise so the only time we saw each other was over the occasional coffee at work. I tried to be a supportive, understanding friend and thought that if I gave her time things would eventually go back to how they were.
But they haven't. Since Christmas Pam has told me a few times that she is no longer so stressed and that her life is back on track. Yet every time I invite her to do something with me she says no. The excuses have included it's too far in advance to plan, it's too short notice, i don't really fancy that etc. She does make an effort to see me at work so isn't completely avoiding me but things just aren't the same.
I've reached the point where I really miss the Pam I used to spend time with and feel like we are drifting apart but I get the impression that she is quite happy with this new level of friendship. I'm not sure whether to be content that I still spend some time with her or to potentially open a can of worms by telling her that this reduced friendship isn't really working for me.
