“You’ll try to convince yourself that being upset is ridiculous. You’ll tell yourself this person was never actually your boyfriend or girlfriend, so why do you care? Maybe you’ve heard something similar from your friends. But if you do care or miss the person, there’s absolutely nothing wrong with that. Regardless of whether you ever defined a relationship with this person, they were part of your life and now they’re not. It’s OK to be upset. Don’t let yourself believe your feelings are invalid.”
