She seems to not be 100% sure of what she wants when it comes to romantic relationships, and is not fully into sexual and physical intimacy all the time. Which is perfectly fine. Many people don't want sex in a relationship and aren't that physical with their SO.

Perhaps it is because she knows you well she feels comfortable with exploring intimacy with you.

This is a sign she trusts you.

Well after a little while we seemed to start doing things a couple does. We go out to dinner, the movies, We hangout and chill.

How are these things specifically limited to couples? Friends do these things all the time.

Now, from reading your post, you do come across as an contradicting asshole.

Things seemed to be different this time around I'm ok with not having sex with her i love her company and just holding her. I could jerk off the rest of my life and be perfectly ok!

But then later while you two were dry humping, you tell her:

"no no no you can't get off while I'm here all blue balls

Then you said she was rude and mad at you until you left.

Dude if I was her, I would be mad too.

This woman told you that she thinks she's asexual, and yet still is willing to be intimate with you. You basically said, "It's not fair that you get off and I don't" even though she doesn't seem to be a very sexual person to begin with. AND you just said a line earlier that you were totally fine with just masturbating the rest of your life.

She trusted you and you were pushy. She had a right to be mad.

You basically said your pleasure mattered more than hers. In sexual encounters, sometimes only one person gets off, sometimes neither do.

She needed someone to be slow and patient with her and you got pushy.
