This is exactly what will happen if she doesn't move out as fast as she can. One of my siblings is partially like this. My sibling had a baby but doesn't want to cut anything out of the busy schedule to make time for the baby. So.... the main caretaking responsibilities are hoisted primarily upon another relative (and to a lesser degree others). Now that relative is so attached to the kid that my sibling uses that leverage to the fullest extent possible.  The only difference is that this relative doesn't live with my sibling and so this isn't a 100% full time thing. Also this relative has had children before (grown now) and should have known better but just allowed it to happen because.... awww it's a baby.  If the 22 year old posting this doesn't run and run fast she is screwed.
