It's a test to see if you really love and value her. After my one and only recycle, she texted, "if you loved someone you'd fight for them!" Uh, I thought, you dumped me. I was quickly making plans to move out and ignoring her desire to remain friends (she didn't want to lose me, but it was more than that).
Recycles take two to tango, no victims in that dynamic. I've been there, and tried years later (with two kids by then). Though hurt and angry, if you're done you're done. If not, move to the Bettering Board.
The less said, the better. Give no targets. Coldly ghosting might elicit more drama, and surely that's a choice, but it might be good to put it to rest with a little words as possible.
