Rachel Green's big dream was to work in the fashion industry, so landing a job as a buyer at Bloomingdale's was a huge deal for her. Instead of being happy for his girlfriend, Ross Geller became fixated on Rachel's long work hours and her relationship with co-worker Mark, which was strictly professional. Yet Ross's jealousy not only affected Rachel at work, but also drove a wedge between the couple. Rachel eventually suggested that maybe they should take a break, leading Ross to have a one-night stand with Chloe the copy girl. The debate over whether or not Ross and Rachel were really "on a break" still rages on between "Friends" fans. For Schwimmer, though, the answer is simple.

"People are so passionately divided about whether or not they were on a break," he said on "The Tonight Show Starring Jimmy Fallon" (per Entertainment Tonight). "It's not even a question. They were on a break."

But Ross didn't just show his jealous side with Rachel. When he dated college student Elizabeth, he went on spring break with her so she couldn't meet other guys. Similarly, he was upset with his girlfriend Emily when she spent time with his ex-wife's spouse, Susan, noted Screen Rant. Ross definitely didn't show his positive attributes throughout his relationships.
