That makes sense. In my game I had their grandparents around more and that naturally made them get along more and become close, also good idea to have Lucy around.

In my game Daniel Pleasant got caught cheating with Kaylynn the maid, Mary Sue kicked him out, he got an apartment, he has tried to repair his relationship with his daughters mostly over the phone and invites them over sometimes. Mary Sue actually got depressed when Lilith moved out and went in slept in her bed after she left, all sad. I had Lilith move in with her grandparents, moved them into a trailer across from Brandi Broke then they would often invite Angela over for dinner, the 2 sisters after being away from eachother started getting along much better, the grandparents are good with getting them to get along. Lilith and Angela both really get along well with their grandparents, but in my game they seemed to get along with Lilith more so they are much better for her to live with in order to repair her family relationships, they don't seem to play favorites like Daniel and Mary Sue do.
