The custody battle between “Teen Mom 2” stars Chelsea Houska and Adam Lind is far from over. During Wednesday night’s second half of the “Teen Mom 2” Season 6 reunion show, Aubree’s father made it clear he’s going to continue to fight for custody of their 6-year-old daughter, despite failing to get his way in court during Season 6 of the MTV series.

Viewers will remember that towards the end of the season, Adam promised Aubree should would be able to stay with him more often "very soon." Aubree returned home from her visit with her dad and told Chelsea his statement. “He promised me he would," Aubree said. "You can never, ever break a promise.” According to Adam, he plans to keep his word.

“When I looked at Aubree, my child, and said ‘I promise you you’re going to stay with me someday’ I plan on keeping that promise. It’s going to happen someday," he said. "Everything right now is just temporary. Everything. We’re still young. We’re still going through courts."

Despite some viewer’s claims that Adam is only seeking custody of Aubree for the sake of the MTV series, Adam says that’s definitely not the case. “I’m not doing this for the damn show. I want to see my kids,” Adam told reunion host Dr. Drew Pinsky. “I don’t have to give you guys an answer why I’m doing this. I know why I’m doing it. I’m doing it because their kids love their daddy and they want to be with me."

Adam, who has 50/50 custody of his 2-year-old daughter, Paislee, with ex-girlfriend Taylor Halbur, said he’s already spent $40,000 on a lawyer in his attempt to get custody of Aubree. “I plan on keeping going until I have custody,” he said. “Promise you that.”

While Chelsea made it clear she doesn’t think her ex has changed his ways and that his issues with alcoholism still concern her, Adam says he believes he’s a change man. “I’m starting to come back around and be who I know I could be,” he said. “I don’t have to be prove anything to anybody. I don’t own anything to anybody besides my kids and that’s what I’m doing.”

While Adam said he’s going to continue to fight for custody of Aubree, he revealed that he doesn’t have a problem with Chelsea’s live-in boyfriend, Cole DeBoer, acting a second dad to his daughter. “If he’s a good influence on Aubree’s life why would I want to take that away from her?” Adam said after being asked to share his thoughts on Aubree wanting to call Cole "dad."

“I like the dude,” he added. “He’s a good kid, good guy.”

Similar to his statements made during the reunion special, Adam recently opened up to the Examiner, saying he feel he’s a change man. “I sat eight months in jail for my DUIs, paid all my fines, followed the law and stayed out of trouble. I was let off early for good behavior. I've made a lot of mistakes I know I can't take back and can only take responsibility for them and own up to them. Now I'm just trying to make a better life for myself and my kids,” he said.

Adam said he now works as a personal trainer and has recently purchased a home. He is dating someone new, a girl named Stasia, and is planning to write an autobiography. As for his girls, he is continuing to settle his custody situation with Chelsea. “I have rights to Paislee, settled out of court with Taylor. Chelsea and I are trying to work through visitation and custody rights for Aubree out of court. ”
