Thank you for your replies. That's the thing, she may apply to other characters when she express her being not comfortable in a love triangle situation, she still refuses, even with Karlach. This, and because of not wanting to be a spare lover line, I personally came to a completely different conclusion. For me, this and the stuff that happens in the third act contradicts each other. You're absolutely right about communication being the key. My main complaint is that I didn't have the clarity and there is a lack of communication in that regard, and for me, it was a low blow.
There are certainly some things in act 3 that suffers from a bit of a rush and the late decision to include a character with a polyamorous romance path that didn't merge seamlessly.
But, the thing with relationships is that there are always could-have-been moments that just never happened because it wasn't the right time. In act 1 and 2 she is also still having a personal conflict between her feelings for Tav and her Sharran ambitions, so she might just be looking for a convenient excuse to convince herself that it's never going to work and bow out.
