I think they'd look something like this:
1. I won't quite my hobby to satisfy the short term emotional ups/downs of my partner.
2. When my partner threatens to break off the relationship or to kick me out of the house/apartment
I will not discuss problems she has with my behavior.
That sounds much more under your control

Maybe we can even fill out #1 some more:
"I am the only one who chooses how much I participate in my hobby. I might choose to continue, or I might choose to quit. I am a choicemaker and I take responsibility for my choices. People can tell me their opinions, and I decide if I take them into account.
When others tell me how much time to spend on my hobby, I will ______ [say "thanks for the feedback"; take a break from the conversation; say "I don't have plans to quit"; not engage with that statement; change the subject; say "I plan to talk about it at my next therapy session; you're welcome to come if you want".... etc]"
Something to give that "rule for yourself" some more dimension, so it's integrated into your life and your sense of being a responsible self.
Obviously, the above isn't something to explain to your partner (not verbatim). It's more some ideas for how you personally can continue to get clarity about your own values and beliefs, and feel strong and secure in your values and beliefs.
I keep going back to the first post in this thread on
Boundaries and Values:
Upholding our values and independence Values. A healthy relationship is sometimes described as an
“inter-dependent” relationship of two
“independent” people. Regardless of the type of relationship, we all come to it with values that we intend to honor and defend regardless of the nature of the relationship - these are known as core values or independent values - this is what defines us.
We also have values that we are prepared to mold and adapt as we blend with the other person in the relationship - these become inter-dependent values - this is how we grow together.
Having a healthy relationship takes a great deal of self awareness and knowing:
- which values are independent, core values to be upheld by us and defended (in a constructive way, of course), and
- which values are more open for compromise or replacement based on our blending with and building a relationship with another person (partner, friend, relative).
Independent core values Identify and live your personal values! Independent core values determine our decisions and guide our lives. It's important that we stay true to them- they should be clearly reflected in the life choices we make. Those who value their individuality take responsibility, are self-reliant and act with self-respect. Those who value truthfulness cannot bring themselves to tell a lie. Those who value family or friendship sacrifice their personal interests for the good of others. Those who value goodness cannot bring themselves to do something they know is wrong. We express values in our relations with other people when we are loyal, reliable, honest, generous, trusting, trustworthy, feel a sense of responsibility for family, friends, co-workers, our organization, community or country.
Be realistic Being realistic about values is important. If we have an unusually large number of uncompromisable independent values / core values, we may be too dogmatic to have a relationship with very many people. At the same time, if we have so few independent values, or such a weak commitment to them, we will then be "undefined" to ourselves and to others. When that happens, the only values that matter are those of others. The latter is common in codependent or enmeshed relationships.
We get to decide on our personal values for ourselves. We may have values around something that not many others do. We get to decide how rigidly or how flexibly we hold those values and commitments. I guess all that is to say -- it's fair to have a strong personal value about your hobby. It isn't something being "done to you", it's a choice you're making, and ideally, you'd be with someone who could compromise in that area (and who might have strong values in other areas, that you would compromise in). Accepting the outcome of having a strong personal value can be difficult. We pay a price to have strong values.
Like the example shared, when many of our values are uncompromisable, the price we pay can be isolation. And when we have few or no strong core values, we're kind of a blob of nothing. The grey area in the middle can be difficult; how do we decide where to hold strong and where to compromise. It is not easy.
I definitely had some values/beliefs/ideas about my H's kids and their interests/values/identities where I've had to compromise in ways I did not think I ever would, for the sake of maintaining connection and relationship. Fortunately, they have not demanded "if you don't do it like XYZ, I won't talk to you again/interact with you again", so I think they have sort of compromised, too -- they aren't happy with how I navigate certain situations, but they don't incessantly focus on "do it like this or I'll never spend time with you".
If it got to a point where they were saying something extreme, like "renounce your spiritual belief that is different from mine, or I'll never talk to you again"... that would be hitting a strong core value for me, and I would hate to be in that position.
All that to say -- You're a choicemaker, you are responsible for your choices, and values compromises (where to bend, where to hold firm) are not easy. Processing the fact that you may have loss and pay a price for your values -- that can help, in a weird way.

If I'm tracking with #2 correctly, you're saying: "When my partner threatens to break up with me, and brings up problems she has with my behavior, I will choose not to continue that discussion or engage with her statements". Is that close?
What could you do or say if/when she threatens to break up and brings up a problem about you?
I'm thinking along the lines of -- not rewarding that with attention/engagement, not engaging with the content, saying you're headed to the store and will be back in an hour, stuff like that?
I'm assuming she's heated/escalating when she says stuff like that?
