"She insisted on it. There are too many issues that are unresolved," a friend of Lopez told PEOPLE, before adding, "She has been pretty miserable and didn't think it was in her best interests to stay with Alex."

It was a tough decision after the couple initially announced that they were working through issues and were planning on staying together last month. However, struggles during the pandemic lockdown took a toll on their relationship.

"They both liked spending more time together as a family, but it was difficult to keep that special spark when they saw each other every day," another source said. And while infidelity wasn't what led to the split, "she won't tolerate the fear of it in the air between them," added an additional insider.
