Hi Cosuffer,
Congrats on coming along so far in your recovery! That is really good news. Your holiday sounds like it was very nice as well.

I wouldn't read too much into the unblocking by your ex. There are a million reasons why she may have done that, and none of them, in my opinion, will make a difference for you.
You've clearly moved on and she will do what she does—blocking or unblocking has no effect on your life anymore.
