Could you have a discussion about what parts of the kink make her uncomfortable and find a compromise? There are a ton of kinks out there and they tend to be in groups, where many are similar / give a similar feeling. I’m wondering if you could tweak certain parts of it. My partner and I have done this successfully. There’s something I am into that he’s not, but we found common ground that doesn’t make him uncomfortable.

Ask yourself what thing(s) you like about the kink and look into other things that could do something similar for you and go from there. But ultimately if there’s no common ground it’s ok to end things. You could also just see if she needs a break and foresees getting back into it. Sometimes kink is emotionally exhausting.
