Bottom line: he wasn't an enabler.
In a new interview with Australia's "Kyle and Jackie O Show," Kyle was surprised to hear that Demi and Wilmer have been dating. Demi explained, "A lot of people don't. Like, I'll post a picture on Instagram and all the comments are like, 'They're dating?!' Yeah! It's been years!"
She explained their relationship over the years, saying, "There were some moments, like off and on, when I was struggling with my issues and things like that." But Wilmer has stood by her during even her "worst times," as Demi explained, "No, what he would do is he wouldn't enable me. So he'd say, 'I can't be around if you're not going to get yourself together.'"
Tough love, but he's been such a huge supporter for her good health. Demi added, "It made me fight for it. Luckily, it was enough for me to keep holding on to. He's a very, very good guy."
