Each persons review opinion is different, just because one person finds her to be the best ever doesn’t mean the next has too. If the op had communication then it just stopped then that’s bang out of order either way. If he had been rude before, changed name number etc a simple sorry I won’t see you wouldn’t go amiss.
I once got a message saying sorry I know you in another life, to this day I have no idea who it was, but at least they was polite enough not to ignore me
