You can certainly care for your partner, but you don’t care ENOUGH.
I’ve cared for the men I have cheated on. I have loved each and every one of them in my own way.
But I didn’t love them enough to be faithful.
You can certainly care for — and love — a person you betray. You can obviously have feelings for this person. (You two are in a relationship, after all.)
But you don’t love him or her enough. If you truly loved this person with all of your heart, there would be no one else. Other men or women would not even exist for you.
It’s understandable that you don’t want to give this person up. You love him or her. You want to be with him or her.
But this is what you need to understand: If you cannot sacrifice the touch of another person — if you cannot resist the physical urge to screw someone else in favor of honoring your relationship — you do not value that relationship enough.
You can feel that love, but it does not burn brightly enough. If you cheat on someone, you simply don’t love or respect that person fiercely enough.
Allow me to restate my thesis: YOU CANNOT CHEAT ON SOMEONE YOU LOVE. IT IS IMPOSSIBLE.
I should know. I’ve been there.
