Don’t mean to discourage you! Just help. I’d like you to eliminate one terrible possibility. That he’s a true narcissist and NOT fixable. There are more out there that you’d believe. Watch some YouTube videos on the subject. Dr. Ramani is among the best. I was married to one for forty+ years and tried and tried and failed to fix my marriage. Just getting some distance has made my life better. Life short! Don’t just work on the relationship harder by yourself. I did and wasted decades. Don’t copy me.
