Would you still be friends with somebody who does not pay attention to you?

I worked with somebody over 20 years ago and we were very good friends We use to have lunch together a lot and even after I found a new job we stayed in touch. We used to have lunch 2 or 3 times a year and used to email each other. Over the last 2 or 3 years I would send her emails and if she responded at all it would just be a sentence or two.

The last time I heard from her was April 2023 and she just sort of blew me off.

I was thinking about her the last few weeks and wonder if I should send her a email wishing her a nice holiday?

This person actually surfaced last week. She doesn't work at the hospital anymore so that is why she never got my emails. Now we are playing phone tag.
