First time poster. I have a close friend in the same town who has been a constant in my life for a decade-ish. We have met most weekends for a run, swim or cycle followed by coffees and chats. We’ve been on loads of holidays and cycling adventures together. We laugh a lot. She was there for me through my divorce, selling my home etc. We have children of similar ages who left home at similar times. In short, a great buddy. About four months ago she stopped making arrangements to meet. My texts were answered with one liners, and then not at all. I left it a month, then put a note through her door, saying I hoped everything was alright, that I noticed she wasn’t responding and I was sad about that, but I hoped it wasn’t anything I’ve said or done. No response. I asked a mutual friend to contact her, and that friend reported she responded to them as normal and made an arrangement to meet. So I figure my friend is actually fine, but has just decided to pull back from our friendship, without telling me why. I have wracked my brains and cannot think of anything that might have sparked this, other than I recently met a new boyfriend and have had a very happy six months after a decade or so of being unhappily married or single. I miss my friend. And I feel bewildered and sad. Does anyone have any advice for me?
