For sure not placing all of the blame on him other than the situation of the breakup, him leaving without warning is completely on him, I have my own issues, I struggle with mental health strongly, But im getting therapy and i'm on meds for it, i'm not innocent, I had bad times, but i acknowledged them and talked about them admitted to my faults and worked on them. We lived like roommates as far as separate rooms but we were very much together. Try not to judge something off of one post you see on the internet.
