AIBU to be annoyed at my friend. We have known each other for 10 years through work and confided a lot to each other. She gave up work because of ill health and I retired 4 years ago. We ring each other nearly every week and me and have visited her and her hubby a few times but she is getting a bit annoying for arranging for us to visit her then cancelling at the last minute. She hasn't been to ours as she can't manage the stairs to our flat. She never rings to cancel but sends a text to say she isn't well. I don't want to lose her friendship but I'm getting a bit fed up with her.
