Kellys romance

Well, Ive read that she will dance for Shepard in his quarters immediately after the suicide mission if she survives. From what Ive read if you flirt with her to the point that she does feed the fish and if you begin the suicide mission in the scene where your crew asks if you want to start the mission now or wait until Shepards ready (or however it goes exactly) if you choose to begin right away youll save Kelly and a colonist girl dies instead. But, if you wait and do the mission later Kelly dies. If all that happens theres suppose to be a private dance scene with Kelly but, Ive never seen it. I did everything right and at the end of the mission Ive seen two different scenes but, neither has Kelly. I didnt have any other romantic involvement with anyone else through the whole game both times and still got two different scenes with Shepard in his quarters alone and Kelly never shows up. This is the 7th time Ive played through ME2 exploring the different romances and I really dont want to do it again hoping I get things right with Kelly just to have another lonely scene at the end of it all. I just want to know what I did wrong or if this is a glitch and Ill never see Kelly dance. The weird part is when I started playing ME3 Kelly's name is on the memorial with the other lost members even though she clearly survived and was alive at the end of ME2. I even made sure I imported the right game save for ME2 when I started 3 and her name is always on that wall.
