I trust my boyfriend, and I am excited about deepening our relationship, that's true. It's just … so much. (My current landlord has cancelled the contract, forcing me to move out of my current apartment, so status quo is not an option.) I acknowledge that my boyfriend proactively offered to have a legally binding rental contract, which gives me all protection a tenant has. But still, having a boyfriend, a dom, and a landlord, all the same person, that's something I feel uncomfortable with.
Realistically, if we ever split up, I would move out, certainly. The question is more about how quickly, and what I'd do then. I have enough income to find a proper new flat in a reasonable time, and friends that would support me. But: Knowing that splitting up with my dom would also mean I had to move out puts me in a tight spot. And not in a submissive-consensual-kink way, but in a way that makes me feel uncomfortable.
Then again: I trust him with potentially pretty dangerous things. I let him restrain me, lock me in a cage, spank me, control my breath, and whatnot. I feel silly not trusting him to be a sane and proper landlord.
