The Colombian actress, who plays Gloria in the sitcom, announced the split via her WhoSay page on Saturday evening (24 May), saying she wanted fans to hear the truth straight from her mouth.
Sofia wrote: "Nick and I have decided to be apart. We have been having too many problems with having to figure out how to spend time together and because of my work and now his, it's been getting worse and worse, not fun anymore.
"We are still very close but we believe this is the best thing for us right now."
Sofia, 41, became engaged to businessman Nick in Mexico on her 40th birthday in 2012. His proposal came shortly after the couple reconciled following a brief split. They'd been together since 2010.
At the time, Sofia told Lucky magazine of her ring: "It is perfection. If it was bigger, it would be too big to wear. But if it was smaller, I would not like."
Sofia is mother to 21-year-old son Manolo from a previous relationship.
