When you're in a committed relationship, you don't go around entertaing people who flirt with you because you care about your partner's feelings and only their attention turns you on. If flirting with other people still excites you, then don't be in a relationship, plain and simple.
Some people can't be loyal one person. No matter what you do Or how good of a person you are. It's just who they are 👎 Sad... But that's reality 🙆
