do you still need help on this one?
It sounds more like alcohol or drug abuse.
is this possible?
60% of drug abusers and alcoholic hold steady jobs
any issues with money?
The other expert has opted out.
Yes, it is possible that he has a mental health issue that is contributing to his behavior, and that includes alcohol or drug abuse, but there are also some men that dump their wives without any mental health issues.
However, there is no direct way that you can find out whether he has a mental health issue, so it is usually better for you to not dwell on that issue. If he has a mental health issue, then it is his responsibility to seek care for a proper assessment and management. You need to focus on what is important for you and your son.
If i can provide any clarification, please let me know.
