FWIW - I still buy and ship presents to my former MIL, and 2 SIL's. Why? Because they are still my son's family and they had nothing to do with the D. I still love them and always will so it's my own choice to do this for them from my son and I. Yes, things will change, but you can choose how you decide to handle her family and she will choose to do what she wants for yours.
Simple? No. This is a complicated process. The key here is to do what feels right to you regarding the IL's.
I agree it is her choice to do what she wants with my family. But, here's the rub, SHE is leaving me, not the other way around. If I were leaving her, then I would not shop for HER family, unless I thought I was SUPPOSED to or I felt guilty to some extent.
Just making the point that while she professes to want D (new life), she does not appear to want to sever ties with my family.
