Yes, I absolutely believe in synchronicity.
You remind me of a lot of things that were going on in my now dead (but still living on in my head) relationship.
So it's kind of synchronous for me too, to read you.
Sounds like the Universe & your own Life knows what you need right now
The stress you've been under just this week is huge! Wow, I don't know but seems these A's create some kind of force field around themselves that magnetizes chaotic and stressfull stuff. Even things not directly generated by a drunken A, or a tearful, pathetic C (C as in Codependent--us).
And it really plays with your head how they deny everything they do... even the most egregious hurts, and blatant lies. Twists with your head and destroys your thinking. Not to mention your emotions.
I did and still do get a LOT of kindness and sanity here; sounds like you need it too.
