Bi-polar. That's a tough one. I'm hoping she is medicated and in counseling because that sickness is a relationship time bomb of epic proportions. In my experience, they need you during their depression and they love you around during their mania... until you try to pull them back from their mania. That's when they push you away because you're ruining their fun. They make you the bad guy and victimize themselves, ensuring they aren't feeling guilty about anything. At least, that's what I've found in my experience... and it's be one heck of an experience.
She's not unfortunately. She won't take her meds. You are right though I have been made into a complete a-hole to those that don't know me. Right now she's telling half truths and whole lies so to speak. Thankfully some of the people that know us both aren't buying it but still those that don't and only know her half of the story think I'm a horrible person
