In her new book, “The Girl With the Lower Back Tattoo,” actress and comedian Amy Schumer opens up about dark moments in her life including an abusive relationship she was in and her mother leaving her father for another man.

In a chapter titled “The Worst Night of My Life,” Schumer reveals she was in a physically and emotionally abusive relationship. According to the actress, she was in her early 20s and the man who abused her was her boyfriend, Dan. 

“I thought he was the love of my life for a long time but I allowed him to hurt me in ways that I still don’t understand,” Schumer writes. “Dan and I would go to happy hours and get drunk, and then he’d get mad and shove me little. Sometimes from the shove, I’d trip over something and fall, and get hurt.”

Schumer says Dan “felt terrible” after the reported fights but she told herself that the bruises were “accidents.” The actress also says that physical abuse wasn’t the only thing she had to deal with. Dan would often criticize her looks as well.

The “Trainwreck” actress also detailed Dan’s most violent outburst which occurred when he shoved Schumer onto the hood of a parked car. Schumer banged her head and elbow but “didn’t get hurt ‘by accident’ this time.” Schumer says she tried to run away twice from Dan that day.

As the night went on, Schumer says Dan's behavior became more aggressive. According to the actress, Dan tried to break a mug over his head. “I was screaming for him to stop, when he grabbed a butcher knife from a drawer,” she continues. “And that's when I was sure he was going to kill me. It may sound cliche, but I saw my life flash before my eyes.”

Fortunately for Schumer, she was able to get out of the relationship and broke up with Dan a few months later. “I’m a strong-a-- woman, not someone most people picture when they think ‘abused woman,’” she writes. “It can happen to anyone. You're not alone if it's happening to you, and you're not exempt if it hasn't happened to you.”

Schumer is now in a relationship with Chicago furniture designer, Ben Hanisch. In the August issue of Marie Claire, Schumer called Hanisch her first, real boyfriend. “I feel like Ben is the first guy who's really been my boyfriend,” she told. “There are guys who, if they heard me say that, would want to punch me in the face, but yeah, it's the truth.”

The couple has been dating since January and despite their frequent PDA on social media, Schumer still calls love “the scariest thing in the world.” “You want to f------ cry and scream. I can't handle it. Every time we say goodbye, I think, ‘This will have been a nice last week together.’ Or I tell myself nothing is real and he's going to leave me and tell me he never loved me,” she said.

Amy Schumer's book is out now and can be purchased on Amazon.com.
