I think it's normal to be sad and upset by something like that, but if she's already happy there's no reason to keep being sad. Don't allow her to put you in a bad mood because its not hurting her if she's hurt you. I think it'd be best to move on and either stay single for a while to get you mind off of things. Or try to pursue a relationship with a girl who you really like and will like you back. If its still hurting, just distract yourself with things that make you happy. Hope that helps.
