Rehashing the events that unfolded during a Teen Mom 2 season can be a challenge — but Chelsea's ex Adam wanted no part of the candid discussion during tonight's reunion special. In fact, the dad of two told host Dr. Drew that he was "done" documenting his life for the long-running series.

"I don't have to explain myself to you guys anymore — I'm not going to participate in this anymore," the trainer said in a serious tone when asked about his absence from Aubree's father-daughter dance, as seen in the clip above.

The addiction specialist pressed Adam to explain but was met with a lot of resistance, as the North Dakota native said he would not answer any questions.

"I even texted MTV that I didn't even want to come to L.A. — and I was told, 'You better get a lawyer to get out of your contract,'" Adam elaborated. "So here I sit."

From there, Dr. Drew brought out executive producer Larry Musnik, who had communicated with Adam about this West Coast trip, to get a bit of context.

"I said, 'Honor your commitments, because you made a commitment to the show and you made a commitment since the beginning,'" Larry stated, adding that he never said Adam would be in breach of contract. "I said it would be a weird place to just stop now and not finish up the season."

Adam added that the show is all about money for him — and he warned viewers to "stay tuned."

So is this the last viewers will see of Adam? Even though he seemed adamant that he was at the end of this road, Chelsea and her father, Randy, both admitted that they didn't believe Adam would walk away from the program because of the cash.
