A relationship can bring joy and self-growth, but expecting it to be your sole source of happiness will set you up for disappointment. For one, an individual should be responsible for their own happiness; although relationships provide love and support, they also come with challenges. When two people’s habits, preferences, and pasts collide, there’s bound to be tension.
Expecting your significant other's presence to give you a never-ending well of happiness will make it less likely for you to work through tough issues and overlook minor incompatibilities.
In short: It’s not your partner’s responsibility to make you happy, and it’s not yours to make them happy. Got it?
