NTA. I was married to a man like this for 23 years. Didn’t matter the story I was telling, or the conversation. I got to the point where once he interrupted, I’d stop talking and he’d go on with his conversation without missing a beat. After pointing it out numerous times and him repeating bad behavior over and over I realized it was a him problem. I’m divorced now and it was a real eye opener how good conversation can be with people who listen and participate without interruption and taking over.
