First on the bed thing, it's hard to stuff a genie back into the bottle, the thing to do is never leave the bed to begin with. But if you voluntarily leave and then demand to get back in it, it's hard not to look either wishy-washy or like a jerk.
Second regarding your comment to her, well it looks like you know you shouldn't have said it so I won't 2x4 you If you feel the urge to say something similar to her in the future, just remember the chilly reception this comment got from her. Hopefully that'll help you remember why not to say things like that to her.
What you have to remember is that she doesn't care what you think or feel! She doesn't care AT ALL. So, you have to stow all your feelings and emotions. If she starts talking about her feelings, then you validate her. But you do not share how you're feeling. Maybe you can again some day when you're piecing, but not now and not for quite some time.
