My friend she unblocked me after 8 months from everywhere, then sends me friend request on facebook. After I accepted the request she messaged me, I replied to her text and again after 6 days I found that she put my messages to ignore list and she’s not replying any more.
Why did she block you? Sounds like you hurt her and she blocked you, then reached out because she has underlying feelings then ignored you realising it still causes pain.
Behind the behaviour is a need, once that need is met, you deal with the issue.
