Stay strong grok, i know this isnt easy and you are an amazing example for your children. Me thinks W is going through paranoia stage as at this stage they think everyone is out to get them because the guilt and shame is starting to sit heavy on her. As much as she tries to put on a facade of being in a better place the infatuation stage of OM has begun to lose its lustre. I seen you are practicing stoicism for yourself and it seems to be paying off. Your children will see that you are there for them and that is where your emotional energy should be focused. Keep it up and eventually you will realize what your worth is and your children will acknowledge that.
