Tyler Baltierra and his father have been working on improving their tumultuous relationship, but the process hasn't been easy. In sneak peeks of Butch's upcoming special, Being Butch, the Teen Mom OG star reveals a shocking confession that once destroyed their relationship.

"I was never addicted to crack cocaine," Butch said while talking to his son and daughter-in-law Catelynn Lowell. "I enjoyed doing it cause I thought I liked it. I liked that rush."

That's when Tyler fired back, "That's addiction! You're substituting it with something else. It was weird to hear you say, 'I was never addicted to crack cocaine.'"

In another clip, Butch discusses the text message with his girlfriend Nadine.

"When I was locked up I went on a cocaine binge for three or four days," he revealed. "Tyler said something to me and I said, 'I love cocaine more than I do you.' I didn't mean it, but I was thinking maybe I do. I am out there for 4 or 5 days smoking this bull. It rocked them."

When his girlfriend suggested they go to counseling, Butch refused to talk about his past as an addict because "the old guy is gone."

In an attempt to make Butch open up, Tyler showed him a clip from a Teen Mom episode of Tyler discussing his father in therapy. 

"I never did anything wrong to the guy so I don't know why he isn't here," he said in the clip. "I don't think it's my fault, but if he did die I would be happier so I could just really say goodbye and let him go."
