Thank you for your responses. I have a really hard time believing it’s a personality disorder, because he’s not manipulative. I’ve had a couple friends that were borderline and I feel like now I can spot someone borderline from a mile away! It would be pretty ironic if my husband were borderline. I also looked up narcissistic, and to be honest, my husband does seem like this, when his mood takes a downward turn, but when he’s just his normal self, he’s very sweet and compassionate. He’ll stop to help someone jump their car or help an old lady through a parking lot. He’s a teacher and always willing to go the extra mile for his students. Also, my husband’s best friend is a psychiatrist, and I just feel like he would’ve recognized these traits in him long ago. It really does seem like his personality drastically changes when he has these mood swings, and I’m one of the few people to ever see one of his mood swings. I think a lot of people would be shocked by his behavior. I wish I could get him on video, so he could see it for himself what he’s like.
