I know my partner struggles with mental health problems and I let her know that she was the culprit to the downfall of our relationship
How did the breakup come about?
I love her so much, but I knew she was going down the wrong way because she's been diagnosed with schizophrenia. to have a healthy relationship, one must be mentally healthy.
People with mental health issues need care, not blame. Blaming her for your relationship ending is hurtful and cruel. Try to put yourself in her shoes and see what life must be like with schizophrenia before you start tossing out blame.
Now I feel like a bad person!  I didn't mean to attack her.
I didn't mean to make you feel bad! There's always time to apologize and let her know you weren't thinking clearly.  You can still make the choice to treat her with kindness and respect!
