You love her but she must respect your need to manage YOUR relationships, including the one with her soon to be ex-husband who has been a big part of your life for a decade.

This. It's crazy to cut him off, he is the father of your nieces/nephews. Your sister will learn to deal and, eventually, she may be appreciate that you maintained a civil relationship with him.
This also means you will probably have to spend some time with her and her new boyfriend. Uncomfortable for sure, but prepare for it.
