I had a friend like that too he had several mental issues like schitsaphrinia and bipolar but he would always misunderstand something I said and get mad at me and yell and scream at me I told him I pretty much go by the three strike rule we’ll needless to say he put in his last strike and I had to let him go it hurt but now I am over it too , so I know what your going through hun I’m sorry you were hurt , unfortunetly not every relationship we have in this life can survive the test of time.
