It is often the case that individuals have life problems but do not necessarily meet the criteria for any specific mental health disorder. I think this may be the case with your boyfriend. A diagnosis is difficult to pinpoint.
You did not ask a specific question so I will give you my overall impression of the situation. Your concerns, I believe, are correct. There are many aspects of his behavior that are troublesome. He has the propensity to be a danger to himself and or others. Below is a list of major “red flags” that should concern you:
- his behavior is unpredictable;
- he becomes uncontrollably angry;
- he carries a weapon;
- he has threatened to kill others;
- he has threatened to kill himself;
- he is emotionally and psychologically unstable;
- he believes he is possessed by Satan which is indicative of a possible break with reality; and
- he is not truthful. He may be either knowingly concocting falsified stories or he believes them to be true. The latter would suggest that he is delusional. He also seems to be paranoid. Delusions and paranoia are signs of psychosis.
You seem to be concerned about your safety. It is good that you are not ignoring the safety risk but you may be minimizing the potential danger of the situation. This is a relationship that you should consider terminating immediately. Do not hesitate to call the police if you believe that he may harm you, himself or others. Report any threats that he makes against you to the authorities immediately. I would also recommend becoming knowledgeable about the local domestic violence shelters or respite facilities and the procedures for a protection of abuse order (often referred to as “PFA”). You should be prepared if you need to utilize these services.
Encourage him to continue his psychological treatment and medications. You should also consider reporting his behavior to his psychiatric treatment team. Due to privacy laws, they may be unable to discuss the details of this case with you but there is no law against reporting his behavior to them. That information is important and it can help the treatment team to better understand his case.
As I described above, there are many aspects of his behavior that are worrisome and place you in potential danger. If you have a specific question, please do not hesitate to write again. Please be safe and take care.
