I’m talking about an unhealthy codependency that can happen when someone with a developed fight-response pairs with someone with a developed fawn-response. It sounds like you two have a healthy relationship where you can discuss each other’s problems with each other freely. Which is good.

Personally, no I wouldn’t expect my partner to unravel my own personal cPTSD for me. I would work on it myself and with a therapist need be. Discussing my progress and thoughts on my own cPTSD and hearing my partner’s is a healthy thing to do.
