For me, that was definitely true. Much as I hated the loss of my marriage, and much as I loved my ex, the pain of his affair made me look a good look at myself and make some needed changes. We reconciled and had several more good years before he went off the rails again. But by that time, I'd learned to step out of my comfort zone, to be brave. I've done things since my ex's affair that I might never have done if he'd remained a faithful husband - adventurous things, brave things, wild things, difficult things. And I've learned to live more in the moment.
