I don't really have firsthand experience with you or your character, so please keep that caveat in mind.
That being said, while I'm less than eager to suggest that you kill him off (I don't like ganking my characters and not a lot of people that I know do either), I have to agree with Firefly on this one since she basically nailed it.
Your character's interactions and developments have created a considerable degree of OOC conflict and resentment, and have also required officer intervention not once, but twice? To me, that's a pretty big indicator that he's worn out his welcome past the point of feasible repair. I understand your reluctance to go all GRRM on him (you've played him for a year and put in a lot of literary and personal investment), but speaking from an outside perspective, I don't think there are many options left if the situation has gotten to this point.
tl;dr - You kinda gotta kill him, dude. Quietly, prosaically, and not in a way that might demand that he becomes the focus of attention, however temporarily. I'm glad that you've accepted that people are viewing him as a problem and that you're asking for help instead of just telling everyone with complaints to take a flying leap (it speaks to your maturity, because hoo boy have I known people who take the latter approach), but...you kinda gotta kill him, or at the very least permanently put him on a bus.
Then start over. Keep the feedback you've gotten here and from your FC in mind, and I think you'll avoid the pitfalls that you say you've fallen into with Tahla'ra.
Best of luck, whatever you end up deciding, and for what it's worth I'm sorry you're in this position.
