We met in a self-help/ peer support group about 8 years ago but the only thing we had in common was the issue we went there to deal with and I no longer go to the group. She's not done anything wrong and is a kind person but I find her really boring, our lifestyles and priorities, sense of humour and some of our values are really different. I've tried not getting in touch and delaying meeting up hoping we'd sort of drift apart but she won't let go and I although I feel dishonest about staying friends I feel like a selfish cow being resentful about meeting for coffee every couple of weeks when it seems to mean so much to her. She has very few friends although she does have a happy marriage and a job she enjoys. I made a big mistake about 4 years ago taking her up on the offer of staying (with her) in her holiday home for a week because since then I've felt like I'm obliged to stay friends. WIBU to end the friendship and, if not, how the hell do I do it?
