I can relate, though the people that have ghosted me will probably say I've done it to them. But all I've done is mirror their actions.
You mention your friend's husband, I do often wonder if other people are involved when someone starts behaving differently. I would reiterate that texting is not the same as not meeting occasionally and is there anything wrong that's led to last minute cancellations, etc.
I know I've had to cancel a friend on a number of occasions and while I gave very long explanations about the problems I was going through and reassured that I will want to meet up as soon as I can, she's begun 'semi-ghosting' me (is there such a phrase, lol). But I have to leave it because any more explaining would look desperate, and no, that I'm not. I've lost the most important people in my life already, I can cope with all further losses.
