This. You come into the relationship probably because you were attracted by something superficial - their appearance, their kindness, their life choices - but ultimately it’s up to you to decide whether or not you want to continue the relationship after you get to know the person.
Do you wish to see their smile next to you every morning of every day?
Do you worry when they get sick? Do you want to cheer them up when they’re feeling down? Do you wish to support them in whatever they do?
That’s love. A continuing commitment.
