Hi there,
It must feel difficult indeed to be constantly on edge, isolated and doubting yourself. Usually when I reply on these boards, I'll try to explain some BPD dynamics to illustrate that her behaviors aren't your fault, so you don't have to take her words or actions to heart. But this time, I'm going a different direction and will reflect on some aspects of your post that are somewhat unique.
First, you're living in you're partner's home. It's not really yours, and that could make you feel like you're alienated from yourself. It sounds to me like you're a bit stuck, maybe even trapped.
Second, you haven't proposed, even though you've been committed for a decade and you're living together. I'd say you haven't proposed because you don't want to.
There are situations in life where you can feel like things are happening TO you, rather than actually deciding something. Your situation might be that way: you might have moved in with your partner out of convenience, because it was economical, it could be fun, and because it would let her stay close to family. But it might not have been something you really "decided," meaning with true intention. Then time passes, and staying together represents sliding--not deciding--creating some relationship inertia.
And now you're feeling stuck and torn. Maybe you're "comfortable enough" in your partner's family's home. But here's the thing. First, it seems to me like you're in a sunk cost fallacy situation. That's a cognitive bias where people continue an endeavor, project, or relationship based on past invested resources—time, money, or effort—rather than current or future benefits. (Maybe you can tell I was a CFO in a former life.) And here's another CFO-type quandry I sometimes faced: bosses (like CEOs and boards) tend to discount the cost of NOT doing something. It's like nixing an investment proposal because the up-front costs to implement the project seem like a lot, while the company is running well enough today. But that's when I'm prepared with another analysis, which is, What are the risks if we DON'T make this investment? Have you considered that? Because if you don't make a critical investment in the company (or in this case, yourself), you could be wiped out in the future.
So I guess I'd ask you to try an exercise. Imagine you could talk to yourself from five years ago. What would you say to him? And now switch to the future: Project your future self out five years from today. Based on your history and your current trajectory, what are the "worst case," the "status quo case" and the "best case" scenarios? And what do you think is the most likely scenario, based on what you know today? Maybe you have some "optionality" in your scenarios, but if you do, how would you assess whether the scenario is working for you? What would trigger a course correction? Now, what advice would your future self give your current self?
How about this (which is what I tend to do): Imagine what a realistic but "best case" scenario would be for your life in five years. Write it down, mull it over, tweak it if you want, think about it for a week. Then my advice would be, you go make it happen. Sure, it might require some time and effort--maybe five whole years of effort--but the results would be worth it, right?
Here's the advice that my current self would give to my young adult self: "Bet on yourself, and you go make things happen." I'd advise, Bet on yourself, because the only person you can control is you. And I'd say, Go make things happen, because being active and intentional creates a live worth living. How does that sound?



It's completely normally to feel conflicted and confused and contradictory when making a big decision, even without the added complexities of emotional abuse and mental illness thrown in.
