exhausted and confused

so i got divorced recently and it's been a weird journey. my ex was always the dom in our dynamic but when we broke up he kinda flipped the switch on me, started wanting to be littler around me as if like seeking comfort or something. which is fine except now im not sure how to react or what boundaries are left. i mean i went from being cared for to caring for him? and honestly it feels more like a coping mechanism than genuine exploration of power dynamics or roles. its confusing cus i kinda liked being able to take care of someone again but it also feels wrong cuz hes still this big dom that broke my heart and now hes seeking me out as his own caregiver in a way. any advice on how to navigate this without completely losing myself? is it normal to feel like im supposed to be the safe place for him even after all he did? i know its complicated but i need some clarity.
