Menzel has now opened up about the next phase in her life, including being a single mother to their four-year-old son, Walker
"It all sucks. I don't want to keep introducing my son to people and having him form bonds and then take them away, you know. It's bad enough his mom and dad are getting divorced," Menzel said.
