What really gets me is how Dorian really does try giving you an out when you romance him:
Inquisitor: I thought we could discuss what happens…after. Dorian: Ah, yes. After. Dreadful thing, after. Let’s see. Assuming one or both of us aren’t slaughtered along the way, what do you wish to happen? We could go our separate ways if you prefer. I’ve been a port in a storm before. I would understand.
Another example comes after you have sex:
Dorian: I’m curious where this goes, you and I. We’ve had fun. Perfectly reasonable to leave it here, get on with the business of killing Archdemons and such… Inquisitor: Tell me what you want. Dorian: All on me then? Inquisitor: Should it be all on me?
And this revealing bit of dialogue after you have sex and say you just want it to be sex, nothing more, much to Dorian's totally expected disappontment:
Inquisitor: I don’t know if I want more. Wasn’t this a good time? Dorian: I’ve no burning need to stroke your ego. More of the same would not be unwelcome. Perhaps this is something we can speak on later…once we see whether you or I survive this whole business. Until then… I need to go. [Dorian stands and starts to collect his clothes.]
I know I mention this a bit, but Dorian really just primes himself for being let down. It's genuinely all he knows. Well and truly. And it's so heartbreaking that he throws you these lines to use to escape so he can try and minimize the hurt before falling for you deeper to that point in which he can neither easily nor safely scrabble out of.
This line he says reveals so much about him. He's so, so confident in terms of sex, but romance, emotions, the vulnerability... He's lost, inexperienced, and not a little bit worried:
Dorian: You say that like [starting a relationship]'s a simple thing, easily imagined. I have no examples with which to compare.
