If the law is that strict about A's, then how is it about D a spouse who is bi-polar? Maybe she is bi-polar, but maybe she isn't. Unless she has been diagnosed you can't be sure.
She is going to dish the cr@p as long as you take it.....bi-polar or not! You would be surprised at all the ways you can toughen up. She suckered you into thinking you were playing childish games b/c the lights were out. Okay, if your child turned the lights out, then that should have said volumes to you! You need to go farther than just turning the lights out when she doesn't come home at an appropriate time. You need to lock all the doors and turn out the outside lights. If she continues to come home at 2:30 a.m., then you need to have the locks changed without notice. You may think this is going too far, but is it as bad as what she's doing? No, I don't think so.
You have to take a long, honest look at yourself and see the ways you have allowed her to disrespect you without consequences. Next....decide how you will stoop being a door mat and implement the consequesnces.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
