What's one thing your partner has taught you about yourself that you didn't expect?

The guy that I dated in high school taught me selflessness I'd never known anyone like him he would give you the shirt off of his back. We were buying slushies and I asked him for $2.00 he reaches in his pocket pulls out some wadded up cash and hands it to me. I open it up and it's $400 dollars so I was like you gave me too much, and was trying to give it back. He says no keep it, what's mine is yours. In the winter he always wore thermals he said, in case he needed to give a homeless person his jacket.
