Is there something psychologically wrong with my husband? His personality has changed since marriage.?

I think your seeing his real personality. The guy you met before marriage was just for show. I would give him an ultimatum (spelling!) saying either shape up or ship out. If he reacts violently to that then you know you deserve better. If he doesn't go to counseling I guess you can't make him. I don't think you're the reason for his change. Worst come the worst he may be developing a mental disorder, but who knows. Good luck
