Tis better to have loved and lost then to have never loved at all

I feel: drained

They say it's better to have loved and lost then to have never loved at all. Whoever said that couldn't have possibly been in love. I am in love, but I'm starting to question how long it could last with him thousands of miles away from me. It honestly breaks my heart to think like that, but it can't be helped. My life took a turn when I meet Lewis; a turn for the better. I learned that love has no bounds when it's true. I like to believe Lewis and I have true love. So far, our love has lasted a good amount, especially for long distance. We've with-standed cheating, hate, pain, distance. It pains me to think he could be cheating agian.

I trust him, I do, but it doesn't make me think differently whe it should. Lewis is my love, my life, the other half of my sould, but what has happened has scarred out love and the scars are visible to anyone willing to look. Another saying is "love like you've never been hurt". I have been trying to love like that, but it doesn't hurt; the pain is beyong hurting, it's at a stabbing pain, driving deeper and deeper everyday that I can't talk to Lewis. I know exactly how my thinking like this upsets Lewis, but he doesn't understand the pain he has caused. Would cheating bring him the same pain that lies within my heart. It might, but the real question posed ot me is could I cheat on him? And the answer comes quick, and it's no; I could never cheat on him, no matter how bad he has burned me.
So, now the real, honest questoin; is it really better to have loved and lost then to have never loved at all?

Again with my randomness, but I have been questioning several things in my relationship
