Markai Durham from MTV’s “No Easy Decision’

*One of the moms featured on MTV’s hit show “16 and Pregnant” took to Facebook in advance of one of the most controversial episodes in the history of the series, reports the New York Daily News.

The controversial broadcast showed Markai Durham, whose first pregnancy was chronicled in a season 2 episode, making the excruciating decision to have an abortion after finding out that she was pregnant again. The episode, titled “No Easy Decision,” aired at 11:30 p.m. Tuesday, which is an hour and a half later than its usual time. [Watch the full episode below.]

The show featured the young mom making calls to the clinic to ask about abortion methods, and tearful discussions with her boyfriend about whether or not to keep the child.

“I thought I was on birth control,” she wrote on Facebook. “I thought I was protected I thought this would have never been anything I would have to go through. But it just shows you … you will never know.”

Durham said she allowed her abortion decision to be featured on the show to encourage more civil discussion on the issue.

“If your pro-life I understand. If your pro-choice hey Im with you. If your anti-abortion I was you. Each and everyone of you I listen to. Even if its only calling me names or disrespecting me because of my decison. (sic),” she wrote early Tuesday morning.

She said her tough choice came down to what was best for her first child – financially, she wrote, there was no way she could afford to have another child. But the debate is sure to ignite discussion for a show that critics have accused of glamorizing teen pregnancy (though many have also credited the show with lowering teen pregnancy rates).

Before her episode aired last night, reactions to Durham’s Facebook post were relatively positive.

“I’m 100% pro-life, but I’ll admit, it takes a lot when you’re a public figure to come out & admit that,” one poster wrote. “I’m not here to judge. I wish the best for you & your family, God bless. Xo.”

This is the second major controversy an MTV show about pregnant teens has had to face this month.

“Teen Mom” star Amber Portwood has been dealing with legal woes stemming from fights caught on tape with the father of her child, Gary Shirley.

The young mom was arrested on Monday after a judge tacked on a felony to a litany of misdemeanor counts she had been charged with last month.
