So a very good friend of mine moved away a few years ago. She now lives about 3 hours drive away. We’ve kept in touch by (mostly instigated by me) and until the pandemic she’d come to stay for the weekend a few times a year - always had a great time. I’ve also been to hers . However she’s cancelled things at the last minute a few times when something else/better comes up. Sometimes she just doesn’t reply to texts at all, By text I’ve told her about a few health issues I was having and when she eventually replied, she made no mention of it and hasn't asked since. I wonder if maybe I’m just missing something and should maybe just let the friendship drift. I’ve also checked all is ok with her and she’s said yes.
