America’s sweetheart Carrie Underwood and her hockey player husband, Mike Fisher, are sadly headed for a divorce. A source told In Touch that the obstacles these two face behind closed doors are driving them apart. “She and Mike love each other, but like any couple, they’ve had challenges. So much so that at times, Carrie has been at the breaking point,” the source said.

These problems haven’t just started, either. Ever since the pair got together, they have spent a lot of time apart. The source explained, “Just by the very nature of their jobs, Carrie is gone on long concert tours and Mike was away playing for the team a lot.” But it’s not like the 34-year-old country star wants this to happen. She wishes the couple could find the time to spend together, but even taking quick getaways has been difficult.

“Carrie has wanted more quality time with Mike. They’ve only been on a couple of vacations together in the seven years they’ve been married,” the source added. Mike retired from playing professional hockey in 2017, but announced that he would return to the ice last month. He’s actively trying to help his old team, the Nashville Predators, make it to the playoffs this season, which is just another added stress on his relationship with Carrie.

The source continued, “She really thought that Mike’s retirement was going to give them the time they needed to work on making their family stronger. His decision put a huge strain on their marriage. If Carrie and Mike continue to grow apart, it will surely end in divorce for them. And that would be heartbreaking.” Carrie and Mike are parents to two-year-old son, Isaiah Fisher, but she’s been hoping to give him a sibling for a while now.

With Mike back on the ice, that could crush her dreams for another child. “Carrie’s been desperate to have a little brother or sister for Isaiah. But she’s been struggling to get pregnant. She was hoping Mike would become more involved in the process of possible IVF treatments, if it came to that,” the source explained, before adding, “[Mike] isn’t always cognizant of Carrie’s feelings and needs.”

In 2015, Carrie opened up about how her marriage actually did change after she gave birth. She even hinted at the fact that it’s harder to keep the spark alive once a child is involved. “Your marriage does change a lot when you have a baby — it’s a whole new dynamic,” she shared. “You have to make it a point to not lose yourselves as a couple. There’s so much going on it becomes easy to not focus on your marriage anymore.”

Carrie’s faith is important to her, so ending the marriage would destroy her. But if Mike continues to neglect her, their future together doesn’t look bright. The source said, “If Carrie and Mike continue to grow apart, they will have no choice but to divorce.”
