Thank you for your responses as it helps me to better understand your husband and his sudden change in behavior. It is doubtful that your husband is suffering from severe disorders like a Personality Disorder, Bipolar Disorder, or a Psychotic Disorder as his symptoms are not consistent with that. In order to have a Personality Disorder, he would have had to act like this for most of his adult life and I doubt he would have been able to hide that from you. A Bipolar Disorder requires mood swings and so far he does not display that. Also a Psychotic Disorder would require symptoms of hallucinations, delusions, and disorganized behavior/speech where he would not be understandable and that does not appear to be the case here.
Most likely what your husband is experiencing would be a mood disorder like Depression with Anxiety. Depression and Anxiety typically co-occur together (around 65 percent of the time) and this would explain his sudden mood changes, irritability, anxiety, impulsiveness, and cognitive issues (forgetting things and partial disorganization). While he says that his change in behavior was because of your post-partum issues, I doubt that was the chief cause because you stated that he was a very prideful man and cannot admit when he was wrong, so when he lost close to 750,000 dollars in a business venture, this may have hurt his pride so much that it caused this depression and anxiety because his ego did not allow him to admit his mistakes here and accept what happened, so instead he decided to run away from this and you. Depression and Anxiety from these unfortunate events can cause a person to run away instead of dealing with the issue head on and that would also explain his change in religion as he wants to find some direction to go that is different than what he is experiencing now. So overall most likely your husband is experiencing a mix of Depression and Anxiety because of these unfortunate events that overwhelmed him and caused him to run away.
While I know you want your husband back, the unfortunate part is that the only way for you to get your husband back would be for him to accept that he is suffering from the Depression and Anxiety and must be willing to treat this issue, instead of running away. Only he can choose to seek treatment and if he does not than the sad news is that you may never get your husband back.
