"I'm very happy, I have my best friend back, so it's cool," McCord said during her appearance on Tuesday's Allegedly podcast with Theo Von and Matthew Cole Weiss.
The pair dated for three years before breaking up in December 2014, but Purcell's 2015 health crisis pulled them back together.
Purcell, 46, had skin cancer, bringing McCord "back into his life as his friend."
"I came back into his life as his friend, and I took him to his doctor's appointments and I was there with him because whether or not he realized it, I love him," the 90210 star said. "One of the things he said was, 'You really love me, don't you?' I was like … 'Oh my God. Are you kidding me? Are you kidding me? After all this time, you still don't know that? I gave up all my 20s for you!' "
McCord said some of the couple's original problems stemmed from his trust issues with women who took advantage of the star and assumed that Purcell is "not intelligent because of how he looks."
The star insisted the exact opposite was the truth, adding, "One of the things thats sexiest about him is how incredibly intelligent he is, and well read, and prolific and a big thinker."

So is a walk down the aisle next for the couple? Not so fast.
"For me, I like the idea of taking your time with things," McCord insisted. "Clearly, we're not going anywhere. There's a lot of pressure from everyone in the world."
Purcell, who was married once before and has four children with his ex-wife, is a little more traditional though.
"If the question is asked, I will definitely say yes," she admitted. "I would love to just let life happen. … I'm not pushing back on it, which I used to do. … I'm open to it, we're not there yet. But, you'll be the first to know."
