This, by Girl on the Net, is very good.

Love doesn’t hurt you on purpose. Love does not repeatedly make selfish choices that will damage you physically or emotionally. It doesn’t yell at you, or lie to you, or gaslight you or tell you you’re worthless. Love doesn’t vote for someone who doesn’t believe you’re a person. Love does not sit hand in hand with those who hate you. Love should do its best to lift you up.

Love might make mistakes, sure. But actively practicing love means learning from those mistakes, not making them over and over and then wheeling out ‘I love you’ with ‘I’m sorry’.
