Why does my ex keep blocking and unblocking me?

Mikeythom
So my ex and I split this past April. About a month after, she started dating someone she met on tinder. They’re still together now. She had me blocked on Facebook since May. Since September she has blocked and unblocked me on Facebook 4 times now. I don’t want her back like I use to. Just trying to understand her thought process here? I have not contacted her since June. And have not acknowledged her blocking and unblocking in any way. Anybody have an ex that did this while they’re in another relationship? It’s starting to look really desperate on her end.
