When I proposed to my fiance Stacy last year, I knew 100 percent certainty that she was the person I wanted to spend the rest of my life with, otherwise, I wouldn't have done it. Justin Bieber has admitted that he wasn't sure he could be a faithful husband...

Now, knock on wood of course, but Stacy and I had been together for two whole years before I proposed and I knew for at least a year, year-and-a-half that I wanted to marry her and spend the rest of my life with her and only her. I never questioned if I was ready for that and I certainly never questioned my ability to remain faithful. I hope this post doesn't come off too judgemental. I'm actually really curious to know what JB's headspace was. I mean, can you love someone enough to marry them and STILL question whether or not you could be faithful?

Here's Justin with Ellen on Tuesday talking about just that...

Now, also, they got engaged not long after his split with Selena Gomez, so it was probably a pretty hectic time emotionally for the guy. Regardless, I wish them well.
