What boys say: You shouldn’t be with him, he doesn’t deserve you. I could treat you way better so you should be with me.
What girls hear: I’m a condescending asshole who feels so entitled to you that I’m completely disregarding your decision-making faculties in an assumption that I can make better decisions for a human being than they can.
Women aren’t lost, misguided little souls looking for the right guy to set us in the right direction. We are competent humans in control of our own destiny, fully capable of making our own decisions about which people to let into our lives.
