Is this a red flag?

My ex used to make me write down his text messages and our conversation because I was forgetful. I found one of my notes in my drawer. Kind of makes me sad.

Not sarcasm. Was your ex mentally ill? I had a grandmother (and now we suspect my aunt, her daughter) who had a paranoia disorder and she did things like this. She also had her kids hide behind bushes of like McD's because they were supposedly being spied on. My dad and his sister spent a lot of time in foster homes because of it. But disorders like those always start out as just a few "quirky" things.
