Melissa Joan Hart revealed last weekend that she and her husband of nearly 20 years regularly go to couples therapy, which helps them have a "safe space" and "understand" each other. "We’ve been in and out of couples therapy and we really enjoy that because it just helps us understand each other better even after 20 years," the "Sabrina the Teenage Witch" star, 46, told US Weekly on Saturday at the nostalgic 90s Con in Connecticut. "We do it once in a while." She said she and husband Mark Wilkerson, 46, have gone more "consistently" since last fall. "We kind of go in and out of seasons of it, but I just find it to be so helpful because it really kind of helps us have a safe space.
