The former "Cosby Show" star broke down while talking to Entertainment Tonight on Tuesday night as she detailed the downfall of her marriage from husband Ed Hartwell.
Hartwell abruptly filed for divorce from his pregnant wife of seven months and said his only priority was getting a "paternity test for the baby."
"This is about my character — my integrity as a woman being attacked — and that's not OK," she said through tears.
Pulliam claims she was the one who wanted a divorce when she learned of Hartwell's alleged unfaithfulness but gave the former NFL player a second chance after learning she was pregnant.
"Early on in my marriage when I was faced with this, I was ready to leave. It's not OK," she recalled. "I had divorce papers ready. I presented it to him. ... Once I was pregnant I did decide to give him that one last chance."
"The part that hurt me the most when he filed for divorce was that he had asked me to give him another chance, and I was willing to do that and forgive him, for our family," she continued.
The 37-year-old stressed Hartwell is the father of bundle of joy she's expecting and that she "didn't do anything wrong."
Still, she no longer has any "desire" to start a family with Hartwell and isn't even talking to her soon-to-be ex.
"There's nothing to say at this point," she explained.
"I have to move forward. I have to do what I need to to release the hurt, to release this, and to be happy for me and my baby girl, because the stress isn't good. The stress isn't healthy. And my only priority is her," she added.
Pulliam became emotional again when asked if she still loves her short-time husband.
"I love who he pretended to be," she responded.
"When he said he wanted our marriage, he wanted our family — I believed him. That's why I gave him this one last chance, only for him to pull the rug from under me and blindside me," she said.
Earlier in the day, the actress teased her appearance on the entertainment show on Instagram and said she was ready to share my truth. She added the quote: "Never let anyone steal your joy.
