Exactly. If you can not do things separately in a relationship without one feeling excluded, that is not mature love. In mature love, both parties know and understand that each is an individual and must be able to have a life outside of the relationship. You do NOT always have to be together to be in a relationship.
Nothing is sexier than a Man who can face temptation and have the level of maturity to say this isn't worth losing what I have…… And a Man who can politely & confidently disappoint other women by informing them "I'm sorry. I'm in a committed relationship. AND I LOVE HER SO MUCH."
