"There were moments when I thought our relationship wouldn't lead to a wedding," she tells cameras. "But I'm sure that Steven really loves me, that his love is sincere. I'm certain I made the right decision."
Meanwhile, Steven notes, "It's been a crazy, crazy journey moving to Turkey to be with her and how much we had to sacrifice for each other. And I think that really speaks to how much we love each other. And that speaks louder than all of the arguments that we've had on the way."

But, all these challenges are just going to make us stronger. And I think a lot of people think we're crazy but, we're crazy in love so maybe they're right."
