The Cheaper by the Dozen star split from the former ice hockey player in January (14) after three years of marriage. They have a two-year-old son, Luca, together.
Duff has been pictured with Comrie on a number of occasions since the announcement, sparking speculation they were reconciling, but the actress now insists the former couple still meet up socially as they are close pals.
She tells E! News, "We're constantly seen together and people are like, 'What are they doing? Are they back together? Are they not?' We're really good friends and we have so much respect for each other and obviously Luca is our number one priority.
"I think we got to a point where we were like, we really need to honour happiness and whatever that is and however we need to sort that out or work that out, we're doing that. We love each other so much and we love spending time together. So when you see us out it's not just for Luca, it's because we make plans and we hang out and we don't know what our future looks like right now but we're both doing really good and just figuring out what makes us happy."
