Contact is inevitable as we have D8 and I always told W that she could come around as often as she wished.
Arsene, I would strongly advise you to rethink this. This shouldn't be this open-ended, and without more structure. Your wife needs to feel the consequences of her apparent decision to break up her family, and yet you're giving her total unfettered access to probably the single best aspect of that family.
I'm NOT saying to unreasonably restrict access to her daughter. I'm saying it should have more structure to it, and be more respectful of YOUR time with your daughter.
