Oh, no. I do mean to mention his other exes at some point (Gene, who was nice but separated from Harry because he could tell Harry was running himself ragged trying to take care of him; Jennifer, who coddled Harry a little too much and came to realize it; and Francis, who in the end had physical and sexual tastes Harry couldn't fulfill). And Ginny wasn't bad, either. Harry just didn't feel much desire for her.

But bad exes create more plot!

Their appreciation is part of the reason Harry thinks Draco's flirting is just silly gratitude.

And thank you!
