Relationships How do you deal with a possessive partner?

I would affirm your autonomy not through words, but actions.

Provided that you're acting fairly, just do what you want to do and explain yourself. If she doesn't like it for no good reason, then what can you do.

I understand it can a bit more nuanced than this, especially emotionally, though I still agree with my own advice (from experience with this).

She'll understand what's what in time. And you'll have to tolerate a bit of drama until she adjusts.

If you are married and have children, then it's different if you're single and no children with her, different advice may apply.

If you want to stay in a relationship with her, you can do a working actually now with Moon waxing in Aquarius, programming your aura and hers to let her give you more space.

It could also be psychological, perhaps her parent made a lot of bad decisions and she feels the need to control you to prevent you from making bad decisions. This is just one example. But many problems are psychological and her own self-reflection is needed, you could bring this up with her, in a way that doesn't make her think that you think she has psychological problems, of course.

You need to do a freeing spell, not a binding one. Alternatively, try a Venus Square to improve the overall health of the relationship. Lastly, as NG Lucius pointed out, one element of fixing this is also in boundary assertion.
