catholic school morality class defined love as "the unconditional concern for the well-being of another."
I always found that to be the easiest and best definition.
Whether you're happy with your partner or mad at them because I thought it would be funny to offer him a cherry when I know he's badly allergic... I wasn't going to actually give it to him I was just teasing cause i didn't want it on my ice cream... We both still care about each other and want what's best.
