31M About to break up with my 30F girlfriend as she is quitting her job.

The title says it pretty much, now before you come at me with pitchforks in hand, ready to hang me for being such an inconsiderate boyfriend, please hear me out:

– 6 years in a relationship, the last 4 have been in a dead bedroom (lack of sex and intimacy).

– Since we moved together I've been the breadwinner, paying all the rent or 70% of it, plus living expenses.

– Been on couples counseling for years with two different therapists (which i paid), have told her in a concise and clear way that having the economic responsibility for both of us makes me sad and resentful. She works halftime the other half she tries to make it as a fashion content creator.

well that pretty much sums it up, last two months I just stopped being the usual cheery caring bf and just felt sad and demotivated. We have been fighting a lot since then. I have been very resentful so much that I am beginning to say hurtful things and my perspective of her is being skewed because f my ire. So i am planning to break up on Friday and today she says "I'm gonna quit" and much like the sinking of the titanic, my heart plummeted to the depths of my stomach. I felt a deep sense of NOOOPE not again. I can't I won't be your economic support once more after literal years of telling her to look for another job. Now I feel like absolute shit because ok I wanna break up with her but she's going through this work crisis. What should I do? wait? tell her before she quits? help her get a job? There's way more details on this but thats basically it.
