Has anyone ever been in a toxic relationship that you have been in for so long.. you know it will never ever work no matter what you do.. you two arent just meant to be.. your not attracted to your SO anymore and your not interested in sex with them, you know it's a depressing, abusive relationship and your partner doesnt really care for you like a partner should.. but your to scared to leave.. but your so over the relationship. Has anyone been in this situation?
