I need to know if I'm wasting my time with this guy.

>Met guy in college, instant attraction
>romantic undertones atop friendly interactions
>Graduate without telling him how I feel
>2 years pass and we reconnect after losing touch
>Tell him
>He says he was burned by a previous relationship
>Understandable. Let it go and continue friendship
>Still have strong feelings about the guy
>Fall out of touch again
>Year later we reconnect again
>Confess again
>"lets take it slow" "I have too much hate in me for love right now"
>Once again, leave it be
>Yesterday spontaneously ask him out to the movies
> act friendly all the way to the theater
>In movies
>Cuddle him, hold hands caress fingers.
>He doesn't resist
>Heaven.jpg
>Walking me me home
>Hug him
>"Should I give up?"
>He says nothing
>Tell him to say either yes, no or I don't know
>Says I don't know
>Asks him if he would kiss me
>"No because there would not be any feeling behind it"
>We part ways
>On train home I text "Should I wait for you?"
>"Don't wait for me. No one waits for anyone these days"

What should I do from this point on? How does this look from an outsiders perspective? What does his "I don't know" mean?
