Thats not boundaries, thats just rude and or nuts. Or under the influence.

I mean, she returns your call or text when shes able. But when she does, she should be available! Wth is that, putting you on hold?

I just heard from someone after two years. She was rude to me last time i called, so i never called back. We literally did not communicate since the beginning of the pandemic. She called to wish me a hapy birthday. We had a nice talk. She asked me to call sometime.

Maybe this is one of those, "if you love something, let it go" deals.
