That is not emotional validation. What is(was) her emotional state? Was she sad? If you were in her shoes would you be sad if you felt like she didn't find you attractive? Stop acting like a typical guy.
"That must make you sad." "Does that make you sad?" etc....
And then, there are so many levels to why she FEELS this way. I am sure you are not giving her the attention she desires.
I still fall back to the art of seduction when dealing with my lady. Read that book cover to cover many times and take notes. Change your behavior accordingly.
