I don't think it is particularly healthy to be in a relationship where the other person is angry when you feel happy. That doesn't seem... Supportive, at all.

It sounds like she needs help... So she isn't quite so dependent on you. So she can develop her confidence in other peoples company and / or feel happier with her own so she doesn't mind you going off to do your thing a bit more.

If she won't / can't... Maybe you guys won't really work out. For the longer term.
