TL;DR: My dynamic with my Daddy may have to make a huge shift away from how it started and it hurts to admit it.

Daddy and I's dynamic started out as a DDLG dynamic and I think that maybe be coming to an end. I regressed when I didn't mean to tonight and I think that messed things up with my Daddy. For context, we have two kids our youngest being an infant... he didn't want to sleep tonight and was fighting it and I ended up age regressing because I am sick and exhausted and just wanted to feel safe. I don't regress easily and it's been a very long time since I have, tonight was the first time since our littlest was born. Little space hasn't felt like an option in well over 2 years and it's been a fight to feel safe enough or to feel comfortable enough to slip into it. Anyways, it happened. I don't communicate well regressed and I messed up by not communicating what I needed at that given moment and ruined the mood for the rest of the night. I'm beating myself up because I feel like absolute shit, I've apologized and tried to talk with my Daddy but I really don't think it made a difference. I think little space may just be a thing of the past and that it may no longer be part of our dynamic. It sucks, but it is what it is. I haven't felt like I can be his little or that he can be my caregiver in a long time. Other parts of our relationship and dynamic are good, but this has been rocky for far too long. We hit a really rough patch and called off our dynamic to focus on our relationship for 6 months about 2 years ago and my little never really came back once we resumed it. I think that's why it's been so long since I even attempted to feel little around him. I'm sorry about this venting but I just needed it out somewhere. How would you go about renegotiating your dynamic in this situation?
