My 26M girlfriend 28F chose Liposuction over mental health

So this is a little much so please bear with me.

My (now ex?) Girlfriend has had some mental health issues for a long time. Not insulting. Just stating facts.

Over the course of the past year even back to January or 24'. She'd accused me of seeing my ex, stalking my location. Showing up at my buisness to see if im working.

It grew worse with her thinking I had a second phone in the house. So she tore all my belongings apart and left me to clean it when I got home from work.

She accused me of wanting to fuck her friends. She's pushed me. Screamed at me inches from my face.

Where it gets a little interesting is over the summer it gets a little worse. She demands my phone and goes through it aggressively and doesn't apologize when there is infsct nothing to hide. Just countless text messages from my repair shop.

She proceeds to fake and STD. Yes. She went to the doctor for a routine checkup and when she got home she told me she had an STD. I was blown away because I've never cheated. In my past relationship. I was cheated on after 7 years. She confessed within a minute and said it was an honesty test.

There are more things She's done but this one was the icing on the cake.

Up to recent events. She's had outbursts in December where she threatened to hurt me.

She came in the room I was sleeping in, and started screaming at 4 am and scared the hell out of me. Legit screaming like she was in pain. I asked what's wrong multiple times and she was upset over a dream. She got more upset and then started screaming at me. I yelled back to leave me alone. When I did she came back and said "if you yell in front of my dog I will hurt you"

While she's screaming her lungs out in front of both of our dogs.

Now up to Christmas.

She applies for medical leave at work. Originally she planned all this medical leave out to better her mental health due to the problems she's been having at home.

Those plans changed when a doctors office in Florida offered a discounted Liposuction surgery. She does not need Liposuction and has never needed it. Told her everyday how beautiful she was. (She is not obese at all for any reference. ) 140lbs roughly.

She wanted to thin out certain parts to be more appealing and fit in clothes. Look I don't care about the idea of cosmetic surgery.

She made a promise to me to get her mental health in better shape for the better of our relationship. Its been over a month since the leave started and she hasn't done anything other than search for therapy and schedule things for February.

She complained specifically about the money involved with therapy. But she spent 4k on Liposuction and a trip to Florida on top of it.

She didn't prioritize what she said she would. I feel lied and betrayed to. Now she wants to breakup because im not keeping up with her expectations.

I don't understand how to communicate with this person anymore.

Any advice on how to proceed would be appreciated

Update! She made a post yesterday I never realized it when I made this one..here it is

Second update- I just talked to her in person and she said that "i could've left the whole time" so I guess the abuse was perfectly rational and it's my fault for staying. /S

I am broken up with her at this point im very relieved.
