This made me feel nauseous because I've been in this kind of relationship. I dated a girl who's suicidal and depressed, so she is kinda dependent on me. I did all I can, I reassured her, I comforted her, I put all her needs before mine. Yet everything I did isn't enough to make her move forward. Pain never leaves, it wants to be felt but suffering is a choice. She chose to stay, she chose to suffer and I chose to stay with her. I shouldn't have done that because after that, she subconsciously dragged me down. That caused me to fell into depression. Then I realized that our relationship isn't healthy, so it's time for me to let go because I want to move forward, I want to choose happiness. She didn't let go of me that easily then our relationship began to be toxic, she wanted me to stay while hurting me. That's when I broke down and became angry at everything and pushed me to drop out of college. I wanted her to let go of me because I might hurt her out of anger, and she told me she wanted it. She came into my house and started doing things to piss me off, I snapped and grab hold of her neck (not enough to choke, but to threaten). I realized I got played, she's manipulating me into doing what she wanted. I can't live that anymore. So I shut her out and told her that I don't want anything to do with her anymore. So if you're gonna have a relationship with someone who's mentally unstable, be careful. It's not that easy.
