There was one time I was trying to make dinner for me and my ex (living together). It was like I was cooking through a fog. I had to ask him 10 or more times what kind of cheese we had. That’s not an exaggeration. He would be the type to spike me with something. He was an angry, mentally and emotionally abusive person. There was a lot I went through.
At the time, I chalked the poor memory up to mental illness. But nothing like that has happened before living with him or since leaving him.
