As an argument between Gina and her boyfriend escalated in their New Jersey home more than 20 years ago, he started to become violent. Gina's friend Shawna, who'd come over to check on her, picked up the phone to call the police.
Soon, Gina's boyfriend redirected his fury.
It wasn't until he turned his attention from Gina and began beating Shawna with the phone that it clicked.
"It was such an eye opener to what he had been doing to me," Gina said.
Shawna's reaction was not to cower, as Gina had done in the past when her boyfriend flew off the handle. She fended off the violent man, and Gina helped her.
"I saw then that he wasn't this superhuman. Two pretty slight girls were able to subdue him," Gina said. (CNN is using only first names to protect the women's privacy.)
Shawna had told Gina time and again that her partner was abusive.
"I made all sorts of excuses for him: He was stressed, having a bad day, etc. Mostly I blamed myself for it," Gina said.
Inspired by Shawna's actions, Gina obtained a restraining order, and the police removed him from the home. Their nearly two-year relationship was over.
"I surrounded myself with friends, kept busy, but I didn't get a healthy mindset until years later," Gina said.
To an outsider's eye, the issue of domestic violence can be black and white: Just leave. For those left physically and emotionally black and blue, that zero-tolerance perspective isn't as clear, creating a disconnect between the abused and those who care for them.
When pop stars Chris Brown and Rihanna affectionately attended a Lakers game together on Christmas Day, many were left scratching -- or shaking -- their heads over the potentially rekindled romance.
Brown had been sentenced in August 2009 for felony assault on Rihanna, his then-girlfriend. He was required to serve probation, do 1,400 hours of community service and complete a 52-week domestic violence program.
After their outing became public, CNN reader Daverelentless commented on the Marquee blog, "When he beats her up again (it's only a matter of time), I will not feel sorry for her. Only an idiot sticks their head in the Lion's mouth TWICE just to see if the Lion bites."
He wasn't alone in expressing anger and bewilderment over Rihanna's decision to welcome Brown back into her life. Witnesses to abusive relationships often ask: Why go back?
Katie Ray-Jones, president of the National Domestic Violence Hotline and the National Dating Abuse Helpline, says there are countless reasons a victim returns to or stays in an abusive relationship: low self-worth, financial worries, fear of what the abuser would do if the abused left, even love.
Friends and family are often an integral part of the victim's way out. According to Ray-Jones, loved ones of the abused are the second most frequent callers to her organization's help line, behind the abused themselves.
"What can we do, because she doesn't want to leave?" they ask.
(Ray-Jones uses "she" and "her" because only 3% of the hot line's callers are male. But domestic violence affects men too: A 2010 CDC survey found that more than one in three women and more than one in four men had experienced violence by an intimate partner.)
Ray-Jones said an abused woman will leave a relationship approximately seven times before she leaves for good. The back and forth can frustrate friends and family.
If victims feel supported, they may grow stronger and more confident.
"It's really important for her to make the decision to leave. He's controlling decision-making, so if you seem to control her decision as well, it's not good," Ray-Jones said.
Being supportive doesn't mean telling the abused over and over that they should leave. Instead, offer a listening ear for when they're ready to open up.
" 'I really care about you; I'm your friend; I want to make sure you're OK; and I want to let you know I'm here for you,' " Ray-Jones suggested.
Ray-Jones also notes that if you think an abused person's life is at risk, you should be "very careful" about calling 911.
