I don't think you can 'get her to see' anything. If you follow DB principles, be patient and let things run their course, 'life' has a way of showing WS's what they are doing/have done to their BS, families and to themselves.
But this doesn't happen overnight, and it's not a process you can push, other than not 'enabling' your WAW to keep OM for some needs and keep you for others. In a way, you need to step back and let her begin to feel the consequences, whilst looking after yourself and your family.
