Since the beginning of the year, someone I thought was one of my closest friends has been doing the kind of things you see suggested on MN if you want to drop a friend. She is nearly always too busy to meet / catch up, or she makes plans and then something comes up and she has to cancel. Her text messages which used to eloquent and informative have reduced to one word answers, and when I speak to her it feels like she is often being evasive, no longer sharing personal information. It's also always me that contacts her first now.
Because of lockdown i've probably let this go on for longer than it should. 4 weeks ago I decided not to contact her anymore and see what happened. She hasn't been in touch with me even though we had a vague plan to catch up in person as lockdown restrictions were lifted. I'm now wondering whether to just accept the friendship is probably over and make no effort to contact her again, or to message her and ask why things have changed. Whilst the second option is appealing as I feel like it might bring me some 'closure', I guess realistically I might either get some harsh words because i have unwittingly done something to upset her, or I might get a bland, evasive 'don't know what you mean' response.
Any suggestions about what I should do?
