So it's been 13 months since we broke up. I am 24 she is 23.1

We were together for 4 years. Our relationship was toxic and now I'm out if it I could see it.

She struggled with bad anxiety and depression. And I made it one of my priorities for the past 4 years to try and save her from that so we could be fully happy together.

I would make her music videos for her music. As she wanted to be a singer. And we spent most of our time helping her grow. I felt I was tredding on eggshells.

She would question her life alot and dishearten herself to the point she would worry me and it would keep me awake some nights. I'd always be checking on her. 

She also self harmed in the past too. Her parents didn't want her as a child and neglected her abit and didn't let her perdue her dreams. Until I stepped in and backed her up.

We were happy. But I think I sacrificed so much getting her out of it. I didn't have any time to myself and she relied on me so heavily. The finally two years together I was in some really tough jobs where I was mistreated.

I developed a hormone imbalance and seratonin deficiency. Which I didn't find out about until this year. But I was visibly struggling and told my ex last year, the year of our break up that I don't feel good.

I went from being happy guy everyone loved to introverted and I could barely function or speak. I suffered from extreme brainfog, anxiety and constant fatigue. It was so confusing and I was so lost.

But I had to be strong and my ex told me it's just work stress as well as my mother. They made me feel as if nothing was wrong so I believed them.

It got worse and worse and I closed away from everyone due to the heavy symptoms. Then my ex left... I begged and begged for months as I didn't want to be alone in that darkness.

Her excuse was I didn't put in the effort or gave her attention. So most of last year she was talking to another dude online. She would post tweets prior to our break up about heart break is coming...

She didn't help me at all. She convinced all her friends I let her down and I look like the bad guy.

I feel hurt. Now she's dating some model. She moved on in about 4 months. And is with him... Funny they met on set of a music video and it was about our break up and he was acting me....

She normally goes from relationship to relationship. And she hates being alone. As as soon as I fell ill and off she messaged another guy and reconnects with all friends.

Then she calls me and tells me she only kept me around so she wouldn't be alone. She always posted about being EMPTY even before our relationship and during. 

She even posts about it with her new guy who's so model.

She told me she loved me and wanted to marry me. But I feel I was just a fix to fill this empty void she carries.

What type of person is this? Is this a personality disorder. Like my friends knew something wasn't right and tried to help me but my ex would tell them I'm fine and lead me off the trail.

Unlike her I have been working on myself and trying to get to the bottom of what took me out last year. I've been on different diets and antidepressants and hormone therapy to sort it all out.

Still not 100% there. But I feel like me again and better. But I still just feel like confused as to how a person could do this. She seemed so nice and sweet.

My mother and friends never trusted her intentions as I have more than she gave me.
