The former EastEnders actor, 37, has been with Sarah for 22 years and they have twin 18-year-old daughter together.
However in 2006 he admitted to cheating on Sarah, and he was recently pictured out with another woman.
While he hasn’t confirmed what happened with the 25-year-old blonde, Dean did confess that his future with Sarah is uncertain.
He told the Mirror: “We are in a place where we don’t know what the future holds. No one wants to see pictures of someone that’s been in their life for so long with someone else. No one wants to be humiliated.”
It’s unclear whether the pictures of Dean with the blonde woman caused a break-up between him and Sarah, but he did suggest they are working on their relationship.
He continued: “When you meet someone when you’re 14 or 15 you need to grow up. You might need to together, or you might need to grow separately. At the moment we’re growing.”
Earlier this month EastEnders star Danny Dyer proposed to his partner Jo Mas. Discussing marriage with his long-term love, Dean sadly admitted it’s not an option for them at the moment.
He added: “Marriage is an important thing. Some would say we’ve left it long enough. But we’re not in a place where that’s plausible right now.”
