How long could you stay with someone who doesn't trust you?

Trust can be earnt, and can come back sometimes, but it depends on the person. But you say you've done nothing wrong, so tbh I doubt it. If the trust is gone without you even doing anything, it's unlikely to work really isn't it.

When I say I hadn't done much wrong, I mean I haven't cheated or anything. However the person I'm with has strict boundaries which I've crossed a couple of times- once by getting overly flirty with someone, and once by speaking to someone I shouldn't have behind his back (though in an entirely innocent way).

Anyways, I wasn't asking whether or not I should stay with him- I fully intend to and don't really have any doubts atm. I was just wondering if I'm alone in thinking that I can't deal with this lack of trust not improving over time, or if other people would feel the same. We have a problem and we're not sure how to solve it and that's a bit scary, tbh.
