As others have said, research what other options are available for you, both on AA and on other airlines. Then call them up and POLITELY, as Pat said, ask to be changed to what you would prefer at this point. If they do not get you where you want to be with flights, ask for a supervisor. Since THEY changed your flights, quite significantly, you are entitled to ALL your money back, if you want to book on another airline. They are motivated to NOT give you your money back, so they will do things that they would not normally do without a fee, such as changing dates or even changing the point of origin of your flights. And as I said, if you do find flights on another airline cheaper, just dump AA and go with the other airline. Best wishes!
