Why does he need to keep an eye on the place for her? Even if she wants to move to a smaller place, she could look for a place all on her own.

I don’t think it’s wise to ask soon to be ex or ex by then (they already had divorce process started) looking for apartments and helping her pack and move. In addition telling him that she needs his help with basic tasks is giving him yet another excuse to weasel himself back into her life.

“She needs my help yet again. She can’t manage. Let me see how I can use it for my advantage”. No thanks
