​Getting cheated on by your significant other is a heart-wrenching experience to endure; however, it can also turn out to be a powerful motivator, as this English man, Mike Vaughn, has come to discover.

Vaughn, who at his heaviest weighed 444 pounds, was struggling with his goal to lose weight, or even control it.

Then, the hammer fell: His girlfriend had been cheating on him, to boot. Despite the devastating setback, though, Vaughn steeled his resolve and got to work.

"My life could have gone in one of two ways," he told the Daily Mail. "Go back into a depression and comfort eat and go back to square one, or use it as motivation to really improve my life. I wasn't going to let something like that destroy everything I had worked for, I would use it to spur me on and I did."

Since then, he's changed his diet, committed to his fitness, and has seen major results: In fact, he's now lost 168 pounds—and he isn't finished yet.

"I put everything into my diet and training, and I can honestly say now I've never been happier," he said. "Since then I've found the consistency that I needed so much. Her cheating was a blessing in disguise."

Vaughn completely overhauled his diet by cutting out chips, soda, burgers, and pizza; instead replacing them with water, salads, and regular servings of eggs, fish, and vegetables. But he experienced his first weight-loss breakthrough when, at the recommendation of a friend, he took part in a six-week exercise "boot camp." From there, he joined a nearby gym, where he became a member of a group personal training program.

Since then, his heartbreaking story has culminated in a happy, healthy ending.
