First of all she didn't write, I bet. But even if she did, Throwaway was first and he hasn't stopped since.
She told him to focus on parenting his child and that should only be his focus. But he decided to make it a hobby of slandering her. His fans ate it up posting on her page about her "evil" ways. Flooding her page how she was purposely keeping him from his child when she was the one going out of her way to try and keep their relationship intact.
Future just thought that he can tour, tour, tour and he would see the kid when he sees him, like he does the rest of his kids. He said this in an interview.
It doesn't work that way with Ciara. She got her own shyt going on. Her plans shouldn't stop because he want to play pop up.
