I despite guys like you, seriously. You dumped her because you ASSUMED she wasn't happy enough, very immature. And then you have the audacity to suggest being friends? You should have talked to her first, see what she's thinking and feeling, and then talk about break up together, if it has to come to that (if she actually tells you she is not happy). But since you didn't that means the only person not happy there was you, not her. So if you don't want to be with her, give her a goddamn respect and leave her alone to move on.

She's angry with you and is in a state of shock/resentment. You broke up with her for crying out loud, how did you expect her to react?
What do you even want to resolve with her lol? Do you want her back in your life (pray forbid she accepts).
You're an ass.
