Help needed: I'm going to tell my kids D21, S17, S11 that W has OM in her life now and so it does not make sense for her to hang with us. I need to put up a firmer boundary. How do I say this without making it sound like I'm punishing her. I need to say that it's clear that W is not interested in restoring our family so we will need to stop acting like one.

Any ideas?

Thanks
