We used to be close friends in college; kept in touch mainly through email and FB. After college we'd see each other every few years, when home for an event or holiday.
Three years ago she sent me a FB message with a brief update and asking about me. I had just lost my first baby, born right before viability. I shared that with her, including his name. Radio silence on her end. A few months ago I started weirdly to get tagged to scam/ spam posts on her timeline, along with all her friends. Those were the only updates I'd seen on her profile, so I thought it was hacked and defriended her. Today I get this message from her, the first in three years: "Nickname, you defriended me????

"
I could explain to her why, but I can't do just that and sweep under the rug her completely ignoring my loss.
WWYD?
