WASHINGTON -- The father of Bristol Palin's baby boy says he's been treated like an outcast since the end of Gov. Sarah Palin's run for vice president. 

Appearing in an interview broadcast Wednesday on CBS's "The Early Show," Levi Johnston said he felt a need to "get my side of the story out there." 

A worsening feud has developed between the 19-year-old Johnston and the governor's family in the wake of Johnston's complaints about not being able see his young son Tripp, often enough. Now there is a dispute about whether Johnston had actually lived with the Palins. 

Bristol Palin is Sarah Palin's daughter, and at one point she had agree to marry Johnston, but that is now off. 

Johnston said he "wouldn't call any baby a mistake. I love him more than anything. I wouldn't trade him for the world." Tripp was born Dec. 27.
