It sounds like she is in the official category of "X-GIRLFRIEND". Move on. Maybe you can learn from the experience and don't be mean to people.
If the agency is contacting you, then you should return the call immediately, especially if they are interested in signing you. Waiting too long may make them think you are not interested and will give the offer to someone else.
Its not an ex-girlfriend. Maybe he calls for a bootycall
its the girl that you like and your girlfriend is jealous of, therefore she hates her and calls her your "anti-girlfriend"
wifey?
He doesnt return calls, he doesnt say he will do what he says. He maybe interested but he wants to continue to have his options open. He probably likes you but he doesnt want a relationship. He wants to play the field. He wants to be able to date you, be with you, and others too.
When he calls you his girlfriend.
thanks
Interested
because he likes you more if he calls you and still has a girlfriend. (from a guys point of view)!
You can call her "Meimei" which means "beautiful younger sister" in Mandarin. It is a common term of endearment in Chinese-speaking countries.
Your girlfriend's cheating
There are several things one can say when your girlfriend calls you on the phone. You can ask how their days went, if they want to see a movie, or just ask about their hobbies.
