Me (34f) struggling with wife (36f) of 12 years transition

Hi all, Throwaway because.
Edit because I think the way I worded it was confusing: My spouse was born male and presented as male until they came out to me as trans last September. They now identify as female which is why I am using "she."
Anyway, I have been married to my husband/wife (sorry, not trying to misgender them, just feeling hard to explain if that makes sense) for 12 years. We had a pretty great relationship and we have 2 kids together (10 and 7.)
However, last September she came out to me as trans (meaning MtF.) And it has really thrown me for a loop. Like, I love them as a person, and I have been trying to be open minded and be like "well this is the same person that you fell in love with, but like better because they can be happier and their authentic selves!) But TBH as she moves forward with changes and hormones and whatnot, I find her less and less attractive. I'm just... Not into it.
But also aside from the attraction piece, it just feels like everything always has to be about her and her transition now and I just find it exhausting.
We did briefly try couples counseling in January but quit after a couple of sessions because they thought that the counselor wasn't gender affirming enough.
The kids are okayish I guess. 10 year old son doesn't like it much but he's learned to kind of deal. The 7 year old seems pretty unphased TBH.
Anyway, I do love her but TBH the attraction is just gone and I'm feeling very worn out by this whole drama and what feels to me like her need to make everything about her and her transitions. Honestly I just want my husband back, but I don't think that's happening.
I know she's going through a lot right now too, and I do sympathize but honestly I am just feeling done.
Would I be the worst if I ended our romantic relationship? Or is there something else I should be doing to better cope?
