This is a tough one...as you have known her for so long. Unfortunately, we do teach others how to treat us if we stay silent. By stating your position you give her a choice to smarten up or ship out....But on the flip side you also empower yourself and gain more self esteem...Thus attracting the right kind of friends. Stand up for yourself and let her know how you feel...you never know, maybe she is unaware that she treats you this way as it has become habit...If not, there are many others out there who would appreciate a real friend like you.

Be kind to yourself ffijiisland
