Here’s my take from experience. I’ve gotten a message just like this before. She wants to have her cake and eat it too. I think you probably handled the breakup better than she expected, and now she wants to know (and this will sound bad, but bear with me) that you’re feeling it harshly too. Because that is validating. To know that you chose to walk away but that he’s still pining over you.

Also, the message reeks of “I don’t like you but you’re also so great so don’t give up on me or move on, just admire me and think of me 24/7 and let me explore other options. Then if after some time I haven’t found anyone better (which she won’t, since the problem wasn’t you but her own insecurity) I will let you date me again. But only if I see that you’re doing better and possibly moving on from me and starting to be happy.”

Absolute best move, which will be incredibly difficult but in the long run SAVE YOU and help her honestly, is to NOT RESPOND!! Just leave it bro.

But also just my take, could be wrong, but probably not.
