It's been two years since I got out of the "relationship" I was in, if you could really call it a relationship. Those thoughts of confusion are not doubts, they come with the territory of something new. Especially if you were in a relationship for a long time. Also because the abuser always blames the one being abused so those doubts are also a reaction of not wanting to believe that it wasn't your fault. Hang in there. I hope things look better soon.
