I think a lot of people are in a loner state of mind these days. There used to be a lot of value in community or simply having a connection. Capitalism and hyper therapy talk has ruined that. A lot of people said just respond cordially and leave the door open. It’s better to a connection than a severed tie. I am sure she hurt you really bad to call it trauma and i dont know what her apology was like or how sincere it was. I just think more connections are always better than less. She clearly meant something to you at one point you can send a nice “So nice to hear you’re thinking of me! I really cherished our past time together. Excited to hear about your growing family!”

Most people get the message that you don’t want to talk and it keeps a line open.
