Why won't she just move on?

My boyfriend baby mother keeps on calling him crying saying she needs help with their kid. But the thing is He's not helping her do anything because i don't want him to. We're both sick of her at this point. Why won't she move on? I keep telling her he just wanted one thing from her because he don't do for her nor that Baby.

He says he's thinking about putting a restraining order on her And he needs my help to do it. Since obviously she won't take NO as an answer.
