You love someone when your life is better with them in it. That might sound like a standard, old-fashioned sentiment, but that's the kind of unconditional love that we all aspire to feel and share. You can't say those three words if you don't mean them; otherwise they're just empty platitudes. When you're considering something as important as whether or not to enter into a lifelong commitment with somebody, it's worth asking yourself what kind of person you'll be without them in your life.
