Because this asshole did just that and his baby mama agreed to marry him after his act of cowardice. I love how no one who interviews this couple calls this guy out on his cowardice.

Patricia Legarreta went to the premiere of Dark Knight Rising with her two children, one only four months old. At the theater were three men who would play a pivotal role in her life that night: Jarell Brooks, a nineteen year old stranger; James Holmes, a twenty-four year old stranger; and Jamie Rohrs, her boyfriend.

One man would save Legaretta and her children that night while one tried to kill them, and the final one left them behind as he escaped. After the horrific melee was over, Legaretta would accept the proposal of Rohrs.

At this point, everyone knows that James Holmes was the shooter, who killed twelve people including a six year old child, and wounded more than fifty. You may think that Rohrs was the hero who saved his now fiancée and children, but he was not. Instead, Rohrs allegedly placed his four month old on the floor, and fled the theater. From Huffington Post:

Rohrs said he lost his 4-month-old son, Ethan, in the darkness and chaos of the theater, but got out himself. Then, once outside, he could not initially find Legarreta.

"I got to my truck and I drove across the mall," Rohrs added. "I'm going to call 911 and trying to call Patricia and it's just ringing, and every time it rings I'm like they're dead, they're dead, your whole family is dead."

Jarell Brooks, had escaped danger, but allegedly saw Legaretta struggling with her children, and returned to help them out of the theater, suffering a wound to his leg. He is out of the hospital and okay. (Source) (To contribute to a fund to support Brooks as he recovers, go here: Indiegogo)

Will there be fallout in the Legarreta-Rohrs relationship?

In moments of crisis, the true character of a person will show up. No one ever knows how they will react when faced with certain danger. In the case of Jamie Rohrs, he fled without his girlfriend and children. Would that be the case for many in his situation? According to the news stories at least three other men died shielding their girlfriends from the gunman's terror.

Could you marry a person who left you in the middle of a crisis?

Not everyone is built to become a hero like Jarell Brooks. It is easy to turn away from people you do not know and save yourself. But when it comes to family, every person wants to feel safe and protected by one who professes to love them. It appears that Mr. Rohrs has not quite made it to a point of selflessness that would protect his family.
