“I don’t know who dumped who,” an insider told Radar Online on April 8. “Adam says he dumped her.”
In the past, Adam and Taylor have been known for having an on-again, off-again relationship, but after their daughter was born in Sept. 2013, fans hoped that he would settle down and that in turn, their relationship would be more stable.
“The breakup happened like a week or two ago. Adam moved out. He said he dumped her because she didn’t stop drinking,” the source says. “She promised to stop drinking because he can’t drink with his ankle monitor on and then she didn’t live up to her word. She kept drinking and going out.”
Taylor has never been portrayed as a partier on "Teen Mom 2," but then again, fans haven't seen much of her in a non-pregnant state, so that's always a possibility. However, it does seem odd that Adam, who is known for his wild behavior, would dump a girl for theirs.
Either way, the breakup doesn't seem to be affecting Adam too much.
“He seems fine,” the insider said. “He’s already been hanging out with a new girl.”
