She's giving me no choice. I need to end it but I don't know how

Yesterday it was one of the worst days i'v had in a year.

She asked via text me if she could post a bikini picture and I said I would prefer not, but that I wouldn't forbid her of anything. That answer wasn't enough for her and she kept on going and mentioned a picture I have shirtless that I posted a few years ago, which I did because I was obese and became an athlete and had a full 6 pack with obliques for the first time ever back then.

 She said I was a hypocrite not to like her posting this pic since I have that one shirtless. She also has more pictures I don't like, like pictures on which she is completely nude but just barely covering privates with her hands. After that I pretty much begged her to post the picture she wanted, I didn't care that much about this subject, I just didn't want to argue over Instagram.

She changed focus completely and now the focus was for me to erase that picture I had shirtless and if I did, she wouldn't post hers. I told her to post hers and that we should stop arguing over this.

This kept on evolving to her complaining about who I follow on Instagram and sent me several pictures of people I know and some fitness pages that show women in bikini's and stuff. She started to demand I stopped following those women/pages and became more and more aggressive. By then the arguing had been extending from noon to 1AM, she had already exploded and blocked me on Instagram, called me names etc...

At the end of it, I finally said to her that I was afraid of her ever since she almost bit a chunk of my arm of at that I was sorry for her at the same time because I do everything to her and all I wanted was to make her happy and to be with her and she only wants to fight and argue everyday.

She then blocked me, went on a Facebook group for Bipolar, Borderline, Schizo and other charming types of people and posted a print screen of that message I sent, including my name and link to my page with her description saying as she was talking about killing herself and I did that to trigger her suicide thoughts.

I had to report the post and call her mother at 2AM to try and to damage control, it was hell. We spoke a little after that, she was talking like a psychopath, she had no feelings, remorse or any concern about how I was. I don't think I can repeat all the cussing she did at me yesterday, all because of Instagram, which I don't even use. I haven't posted a new picture there in several months.

I don't know how to follow this. This Sunday we would complete a year together and my birthday is in a couple weeks.

This time I don't know how to end and I don't know how not to end. At the same time it feels like it's been over for a while and we only have a "ghost" relationship left.

I just wanted to give her gift no matter what, I really put thought in it. I value gifts because of their meaning behind them, maybe more then other people. She gave me a mug 8-10 months ago that it was just so well thought out and matched my interest so well that I sobbed for hours last night just remembering about some of her good gestures in the past year and I really didn't want to erase her from my life.

I just spoke to her. She went to her therapist today and her therapist talked about commiting her again. She said to me she wouldn't because of what my family and I would think of her. I told her it was nonsense and I didn't care if she commit, I cared if she didn't and kept treating me this way and being afraid of her killing/hurting me or herself.

Her lack of empathy is mind boggling, she truly appears as if she doesn't care about anything.
