An insider reveals:
"Heather felt like she had been spending so much time with Jack, that it was affecting her child. Ava is at that point where she'll soon be a teenager, and she needs her mom more than ever, especially since she's trying to become an actress and a model. So Heather told Jack she wants space."
It's good that she's putting her kid first, but we wonder if there were other factors involved.
Couldn't she have just scaled back her time with Jack a bit instead of calling the whole thing off?
