You know what's one of the biggest problems with coverts? They're so covert....
It's like they don't send up red flags so much as pink ones. It can take a long time to see it for what it is- as you know.
That 20/20 hindsight can really mess with your head.
I still struggle with a lot of anger, mostly at myself- that I accepted certain things, that weren't okay, as normal or acceptable. Didn't value myself enough, even though I remember legitimately arguing for my own benefit at times (and generally losing).
Even though it hurts a lot, understanding the truth of what was happening is still a good thing, right?
