same for me. my nex made me block almost everyone on social media. after i broke free i got contact again with an old friend. he changed quite a bit through the years and has gotten more caring. after we hung out he left me some really really nice messages. at first it felt uncomfortable and a bit icky, and then i said out loud "i'm not used to people being this nice to me" and the dam broke. i cried so hard and almost couldn't stop crying. i then also realized that on one hand it feels amazing when someone is nice to you, but on the other hand i get very suspicious and almost feel threatened, simply because i do not perceive niceness as normal. i mean, he was with a few messages nicer to me than my nex ever was.
