By all means man, take care of your kids and yourself. You lost me at the "no matter who gets hurt" part.
Avoiding causing someone pain is a good thing, no matter how crazy they may be. You don't behave that way for them, rather it is for you. Avoiding causing another person pain is who you choose to be.
That said, if it is a choice between my kids being hurt or someone else, then that someone else better be ready for a world of hurt.
Now I am not saying you should have done anything for CB from the kids, but you sent that TM because it felt right to you in your gut, I know it all hurts more now that you are getting ready to pull the trigger, and it is something you have fought against for so long, but "In the end, I win." She has taken so much from you brother, don't let her take your self-respect as well.
Ultimately we choose to do the right thing because it is what we beleive to be the correct action, and it is who we choose to be.
Hang tough.
