So I told her I won't be in a part-time relationship
Not sure what the others think...
I would not bring up the relationship. It is ok to refuse to hang out with her. But do not complain about the relationship. Just say you have other plans, and do have other plans. She needs to see that she is no longer your top priority without you rubbing it in.
Same thing regarding her waking you up in the middle of the night. If you think that she needs help and you are willing to listen to her, why not. But if you think she is just manipulating you, you can ask her not to wake you up because you need to sleep. Just do not base your behavior on what you think or want from your relationship.
