Black Robed One

I would like to ask: what is the best way to terminate Darian’s romance as gently as possible and without ill feelings.

Would rushing to rescue Imoen and thus skipping his “special scene” be the best course; or would it be better to wait for that “special scene”, providing that it has an option to terminate romance and start/confirm friendship with Darian instead?

(I am currently playing as a female character who is not interested in Darian romantically, but would like to consider him a friend.)

P.S.

I am also interested in Darian/Aerie romance, so I am looking for a path that wouldn't "kill" it.

First of all, I really liked the idea of this mod; particularly a romance option for Aerie for the case if she isn't in relationship with PC.

Unfortunately, I ran into a few problems with Darian during the installation....

1) During the installation, I don't recieve an option to choose a class for Darian.

2) Darian's installation seems to indiacte that he has crossmod content with Sarah, but his setup doesn't seem to see previously installed Sarah mod (v3.1 - the latest version currently avaliable).

P.S.

By the way, is it safe to manually change Darian's class with Shadowkeeper? Because I kind of prefer to let mages and thief to handle ranged support, and would prefer to see Darian as pure ranger (or possibly Justifier, which I feel would fit his paladin-like image).
