How to be a more supportive partner for my partner with CPTSD?

Hello, all! I posted a little under a year ago asking how I could be a better supportive partner to the best person I’ve ever known in my entire life: my parter - she has diagnosed CPTSD due to prolonged domestic violence from before we met. I also asked how I could learn more about CPTSD and I got a lot of great tips and research resources from you all and I really appreciate all the tips I got! I’m continuing my research as well :)

I return with another question on how can I help my partner feel more supported? I’ve asked her what she needs from me when she’s having a more difficult time than usual and what I can do to help her feel more supported in general and she says she doesn’t really know, so I come to you all to ask: if you have a partner, what have they done to help you feel supported? And what can I do to help my partner more?
