A relationship is kind of like a house in that, after a while, it will require some maintenance. You can’t just commit to it and then forget about it—it takes work to keep it livable. Your relationship will require some effort every now and then to keep things strong between you, and it’s not a good sign if neither of you cares enough to work on it and improve the situation. If you can’t get motivated, it suggests fixing the relationship isn’t important to you.
