Are you going to write Jaheira-romanced dialogues from the perspective that PC is just a short-term fix and Khalid was, is and always will be her only true love? I don't know, but perhaps we should not deprive her of the chance of fall in love again, even if you don't find the way the Bioware romance does it, a credible way.Perhaps, perhaps not. Physical suffering is harsh, but these memories are short term, and Immy is generally such a nice girl ... I think she of all them could forgive at some point, if she sees enough anguish. Jaheira is another story - she had lost love of her life (whatever PC may think and however it may develop later - he is a quick fix, nothing more.)
This is of course down to each owns interpretation, but I wouldn't want my PC's to be made feel like they are only a replecement, only a quick rebound.
