You're not alone in having this sort of story.

Speaking as someone else who survived an emotionally abusive relationship years ago (with gaslighting so successful that I had to start secretly recording our conversations on my phone to make sure they really happened the way I remembered and not the different story she would tell me later), successfully cut my ex out of my life and worked on myself, and am now happily in a truly wonderful and healthy marriage to an amazing person, congratulations on getting out.
