Listen to kp here man.
Don't be this guy you are being. She will walk all over you.
At this stage you don't need her. You have other things to do. Other people to see, other places to go. Bigger fish to fry.
Don't act like this girl girlfriend. Telling her to do what's best for emotionally blah blah.
Let her deal with herself. You look after you.
Don't contact her. And you know what. I wouldn't be in such a rush to answer her calls either. Its not playing games but she asked for space so give it to her. Because right now whether you think it or not you need some space to evaluate this as well. Look after you for a while and as kp said make you the priority! Not her!
