It sounds like this relationship lacks a few things. One is communication. When something upsets you, you have to be able to talk about that and have a favorable resolution. You shouldn't have to avoid calls or leave feeling that you were disrespected. She is definitely disrespecting you. You should have been given an explanation if she was going to do this. It is strange that someone would be working at 1:00 in the morning. That's why you should be able to ask. If you feel that she is treating you like trash you have some decisions to make. You don't have to tolerate someone abusing you. You can let her know that this relationship will have better boundaries or that it can't last. You have to know what you want and ask for it. Nothing will change if you don't ask assertively for what you want. You have to learn how to do that so that you are happy too.
