She was a bad girlfriend for not understanding that you were going through a hard time and reaching out to you more instead of expecting you to help her as you did when things were going bad.

" i always made her a priority "
Then yes, you were wrong.
"I would constantly try to make her happy"
"I never got an answer to what i did wrong,"
Well, you did now.
A relationship is supposed to be between equals. Not a one sided support system for the female.
You made yourself into that, and then wondered why it wasn't a relationship.
You made yourself into that, and she got used to it, and then got pissed off when you weren't there in your usual role.
In the future, don't do that. Don't be that.
