Milestones become bittersweet, like when Jo’s best friend moved out to live with her boyfriend. “I can’t begrudge her for this, of course, and I am happy for her because she is happy,” Jo says. “But it was hard because we had this really good thing going but I have now been deprioritized. This will probably keep happening for the rest of my life because that tends to be what people do. Their primary romantic relationship takes precedence over friendships and sometimes their family.”
