She told me she felt it coming on, that she was checking out, and she didn't know what it was going to be like this time because when it happened in the past she didn't have the context of cptsd. And she's definitely straddling both worlds. One foot in the present, one foot locked in sheer terror, anger, confusion, etc. She's exhausted. She needs help with the kids, and having them with her helps keep her present, she's just not well enough to care for 3 kids and herself right now. Her divorce terms are very restrictive, her ex has first right of refusal if she needs a babysitter and he's available, he gets dibs on watching them if he wants to. So of course he's doing that, because I'm sure he thinks he can worm his way back by being soooooooo helpful. She pretty much hides in the bedroom while he's there if she can.
They also have a trauma bond that hasn't had time to be fully broken. Cycle of abuse shit. He's the only person who has been in her life, they got together as teenagers, so he stayed with her through all the bad shit, so when she's terrified of her own mind and capabilities reaching out to him is reflex. She knows he's abusive, she knows what he did to her, and me, but she said she either can't help feeling like she needs it to be him helping right now, or she doesn't know how to help it. So here we are.
Back to the dissociation, I think she's so stressed and exhausted, it's easy for her to slip in and out of the present to try to cope. Being checked out is easier than facing a lifetime of abuse and neglect.
