I need some relationship advice. I'm in a relationship that I know is toxic, but I feel like I can't leave because I feel like she is the only person that would want to have a relationship with me, and because I'm worried about her hurting herself if I try to leave her. I'm at a point where I don't if I can save my relationship, but I want to still try to save it ,but I just can't deal with everything going on in my relationship. I can't deal with her using drugs again. I can't deal with her lying to me, and manipulating me. I can't deal with managing my mental health, and hers. I just don't know what to do anymore. I just need any advice you can give me.
