Lea Michele "Got No Reason or Explanation" for Split With Matthew Paetz: What Went Wrong?

The actress and singer had been dating her ex-boyfriend for nearly two years

It has been a rocky romantic road for Lea Michele. 

After nearly two years of dating, the Scream Queens actress and her boyfriend Matthew Paetz broke up. While the split is shocking news on its own, the nature of their breakup has incited even more questions, particularly for Michele herself. 

According to a source close to the former couple, the 30-year-old aspiring model left the 29-year-old performer "all of a sudden and without warning" about two weeks ago. He is now refusing to speak with her or anyone else close to her, the source added. 

"She got no reason or explanation for the split," the source told E! News. 

The pair first met on the set of her music video for "On My Way" in April 2014 and were officially dating by that June. Three months later, they had moved in together, sparking rumors of a future engagement. 

"She was also very supportive of him even when her friends were skeptical of him because of his past," the source continued. "Lea wanted to believe in love and wanted to believe the good in him. She didn't think he should be punished for his past."

According to reports, Paetz had previously worked for a service offering male "companionship" for women, though the site's owner had no comment on whether or not he was still employed by the company at the time. His history didn't sit well with Michele's friends.  

"He ended up being an opportunist who took advantage and broke up with her in a very heartless way," the source shared with E! News. "Her friends were always concerned with the relationship because of his past. All of those fears were validated."

It's not exactly the tune people close to Paetz are singing about the former twosome. 

"They've been hot and cold for some time now—one day fighting and the next madly in love," a source close to Matthew told E! News. "Friends believe that Lea's success came between the two and Matthew began to resent Lea."

"The two just stopped working," the insider added. "[He] wanted to get out of town for a bit to clear his head."
