Article with Nick's response to the break-up. Here's the link
I've copied below Nick's part, there isn't much else to the article. I thought it was nicely written.
E! News managed to catch up with Nick after he heard the breakup news, and I gotta say, dude kept it super classy (even though he has more than enough reason to gloat a little).
"I was surprised. I feel for them. Heartbreak is tough for anyone, whether you're engaged or not. It stinks," Nick said.
He also wanted to be clear that he does not feel "vindicated" in any way. "I've been asked that a lot today," he admitted. "But the answer is no. I don't hold any ill will against either of them. I've moved on with my life."
While he's not seeing anyone exclusively right now, he is having fun dating different girls. "I enjoy being out there. But I haven't met that girl yet," he admitted.
Does that mean there's a chance for him and Andi after all?? Apparently not. "No. In a lot of cases things happen for the right reason and in our case it did," he said. "I'm excited about the people I have in my life now. What happened with Andi is in my past and it's going to stay there. I moved on. I don't want to move backwards."
In fact, if he's going to reunite with anyone, it's probably going to be Josh. After revealing that he hadn't reached out to either one since the new broke, Nick said, "Maybe down the line it would be nice to reconnect with Josh as a friend."
There you have it! Nick reacted in the best way any guy in his position could have. I'd say he's redeemed himself from any kiss-and-tell stigma he may have saddled himself with six months ago.
