In an interview with Soap Opera Digest earlier this year, Joshua Morrow was asked to give his opinion on what his character Nick Newman's greatest weakness was. Though Nick's longtime relationship with Sharon Newman and their subsequent reconciliations have been beloved by fans who consider them a supercouple, Nick has had a difficult time staying faithful to one woman. Morrow said, "[Nick's] biggest weakness is commitment. He's had several issues with maintaining a healthy relationship and that comes from his questionable character when it comes to women."

A major contributing factor to Nick's inability to make a relationship work is his wandering eye, which has led to several instances of infidelity over the years. He is particularly known for ping-ponging between Sharon and Phyllis Summers, the mothers of his children. In fact, he cheated on Sharon with Phyllis during their marriage and later fathered a child with Sharon while married to Phyllis (via Soap Central). However, Nick has proven his inability to keep it in his pants with several other women, as well.
