I think it might be the famous "cycle of abuse" thing what's confusing me here. This switching from being the nicest guy in the world to the mean, manipulative, controling boyfriend. I read it on another post and it hit me like a wall.
It is so scary. At first, you trust someone, you let them in, and when they start acting weird for the first time, you don't immediately break it off. Or would that be better?
