I'll give you a direct answer to your question, and after that a better one.
Toward the end of my college years I was engaged to be married to a woman I had been seeing for over four years and was deeply in love with. Our wedding date was fast approaching, the invitations were printed, wedding and bridesmaid dresses chosen, excitement building. Then one evening, purely by accident, I found her in bed with one of her instructors. To use your words, the experience was a crushing and thoroughly devastating. I went completely off the rails. She married the instructor.
Fast forward a few years. I had just completed my military obligation and was regaining some semblance of normalcy when I was introduced to another young woman by a casual acquaintance. A relationship developed and seven months later we were married. That woman has been my wife for the past 49 years. We are as one person and she is my everything. She is the greatest earthly blessng I've ever received. I have absolutely no question whatsoever that this is what the Lord planned for me.
The better answer: The Bible doesn't promise us a life free from pain, frustration, and loss. Quite the contrary, we're told to expect these things. But for those of us who love Him and truly trust in Him, we can rejoice in knowing that He loves us and that all things are going in accordance with His eternal plan. Sometimes we can see His influence on our lives. More often, we'll never understand how the pieces fit together until that day when we stand before Him. For me, my faith isn't a part of my life. Rather this earthly life is just a small part of my faith. If we truly believe and put our trust fully in the one eternal, infinite, and loving God then we can join Paul in saying "I consider that the sufferings of this present time are not worth comparing with the glory that is to be revealed to us." (Romans 8:18)
Might I suggest that you focus on your faith rather than your suffering, TooMuchMuktuk. Maybe you'll find one of my favorite bible verses helpful: "Rejoice in hope, be patient in tribulation, be constant in prayer". (Romans 12:12)
