I tend to agree with JSrombough.

If this was a last minute U/G for the couple, they should have understood that they may not be able to sit together.

I too have my favorite F & Y seats, and have given them up more times than not when asked. I'm not sure if I would be so willing to give up a seat to a far less comfortable one, icy stares or not.

Jackie & I got a last minute U/G on a flight last fall & knew we would sit apart...but our feeling was 'it was more comfortable' than sitting in Y, apart or not.

PremEx, you did the chivalrous thing, but I'm not sure I'd do the same thing, especially on a long transcon.
