I'm married to one and we've been together for about 18 years. We've taken an online quiz and he scored like 22/25 while I scored 4/25. I am not a pushover, for the record. It works for because because I don't expect him to change, I have my own life and interests, and I enjoy listening to people so he has plenty of space to pursue and talk about himself and his interests. It's hard at times but it helps that he's a genuinely talented, brilliant and funny person. If he didn't have the skills or intelligence to back up his big talk, he would drive me insane. He also has strong moral views on marriage so he doesn't cheat or talk badly about me as many with this personality type/disorder feel entitled to do. He sees me as an extension of himself so he wants people to think well of us and our family and he wants me to feel good about myself and do cool stuff in my life. In short, I wouldn't recommend it because 99% of the time it's a hellish abusive relationship, but we have somehow managed to make it work.
