Sad but kinda true 
All good things must come to an end.
I had a long discussion with a friend about Bianca and Varric's relationship. She thought that it was romantic that they were together after all this time, and thought it made sense that she didn't marry Varric as it would have "caused a small war". Personally I find that a poor excuse. If Bianca was really any kind of a decent human being- er, dwarf- she would have done the right thing. She would have either married Varric, or would have done her duty and gone through with the arranged marriage. In making the choice to get married, if she was any kind of decent Bianca would have told Varric that she loved him, but it was time for them both to move on. I can't accept the fact that she's kept him strung along for 15 years, nearly 10 of which she didn't even see him. Those are not the actions of someone who loves another. That's just pure selfishness.
And Varric is a numbskull for letting her get away with it. What kind of a person lets someone do that to them for that long?! It's pure lunacy! The man is sexiness on legs, and yet he lets this person yank him around. *sigh* I'd feel bad for him if he wasn't such a hopeless case.
