Why would my ex block me then unblock me?

So its been 3 months since the break up,2months of fighting after then I went no contact.when I went no contact she sent me a msh that she is blocking me on Facebook I never replied.2 weeks later she has unblocked me.I sent her a message finally that I'm doing very well(I actually am) and that I'm okay with the break up and it was for the best as I'm doing so well now.I also said no hard feelings and we should put this behind us.

She did not reply though.I started talking to another girl and we got close until my ex started spreading rumors about me that finally chased my new girl away.I was told she hates me and wants nothing to do with me.its funny now since she unblocks me she's getting guys to write all over her Facebook wall

So why would my ex block me then unblock me?why would my ex get mad about a new girl?and why would she not reply to my msg

Oh and her bio on Facebook has this posted. "Dear Tummy, sorry for all the butterflies. Dear Pillow, sorry for all the tears. Dear Heart, sorry for all the damage. Dear Brain, you were right"
