Steve is right you W is in full rebellion. She has lost all respect for you.
You are not babysitting, parents don't babysit their children, they shield them and raise them. You are being a awesome dad, while your W is living her fantasy. Please don't call yourself a babysitter.
I will like to add to what Steve has said. It took TxHubby 3 years to get to the point of being completely fed up. I can see you are getting their, but you are not there yet.
Your W needs a wake up call, she has to have reality hit her square in the face. If you are not ready now, you will be tired of allowing her to do whatever she wants around you.
Some things you could do is pack up all her stuff and have it waiting in the garage or by front door. Tell her you are not going to MC until you feel as thou she is ready to work on the M. Until then you will continue to work on yourself.
Tell her to pack her sh$t and get out. She might not leave, but the tone in your voice and the stance of your body will make a huge statement. After you make that statement don't say anything else, turn and leave, the last thing she will remember in that moment is the back of your head and body walking away (out of her life).
She is playing games, and you don't like being part of her game, so pull yourself out of her craziness and work on becoming healthy and detaching.
You can also, just start ghosting her. When she starts to tell you about what she is about to do and where she is about to go, " you tell her politely that you don't care and tell her to enjoy her night". Don't give her time to give you an explanation. Let her start to wonder what is going on, why doesn't he care anymore. Pull yourself out one foot at a time if you have to do it that way.
Oneward and forward
