Memory Loss
I had been dating a baseball player for a little over 2 years, and at one of his games, he got hit in the head with a baseball and got amnesia. Completely forgot who I was.
I tried explaining what happened, but he just couldn’t seem to understand. I was trying to be gentle and see if he would remember on his own, but when he didn’t I just told him we were together. He looked me up and down and said, “I wouldn’t date somebody like you,” and walked away. I tried contacting him, but he completely cut me off. Weirdest and hardest break-up ever.
