You wrote that your gut instinct was he was narcissistic when he was looking in the mirror for an hour (like Narcissus who fell in love with his own reflection) - but the big progress you made here is you felt your gut reaction and listened to it, that's why you posted here. I see that as a big positive to come from all this.

Please don't spend too long thinking about him, as the Maya Angelou quote goes "When someone shows you who they are; believe them the first time."

As has been said you deserve much better.
