I've been up all night freaking out and I need some advice and someone to talk to 
I'm posting this in the PTSD section because this is affecting my C-PTSD.
My best friend has never been very fond of my fiance. She finds him extremely annoying and thinks he's very self-centered. She says he thinks the world revolves around him and that he always thinks he's starring in the "[his name] Show."
The two of them tolerate each other when we all hang out together but you can tell there's a mutual dislike. My best friend has never told me I should break up with my fiance or I'm making a bad decision or anything like that, but my fiance has said I should dump my best friend and that she's "toxic" and he's "sick of her ****."
I felt bad that he said that and I didn't want to be put in the middle so I confided in my best friend about it, and she said "He tries to turn you against anyone that's standing in his way." I really didn't want to admit that she's right but she is right about that.
Earlier tonight I was texting with my best friend and she tried to tell me this as gently as possible but she said she thinks my fiance may be a narcissist. She sent me a link to a site that listed all the symptoms of narcissistic personality disorder, and unfortunately I think my fiance ticks a lot of the boxes
He always talks about himself. If the conversation he's involved in isn't focused on him, he redirects the conversation by talking about himself again. Everything he says pretty much starts with "I." He talks about his appearance and his achievements a lot. He tends to exaggerate. He's always the life of the party and the center of attention. He dominates all conversations. He rarely asks other people questions about themselves. He'll say "Hi, how are you" but that's about the extent of it.
He fantasizes a lot about things like being a famous pop star, driving a Mercedes, having a private jet, being a millionaire, etc. He likes to go to parties where it's likely that he'll interact with rich people and he wears mostly designer clothes and an expensive watch and stuff. Everything we buy has to be "brand name" and he spends a lot of money on things like wine, champagne, etc., not to mention clothes and shoes! He's not good at managing money and we've had some fights about it. He gets really upset when people point out that he drives a minivan.
My fiance is pretty critical of my friends, particularly the ones that are awkward or nerdy, or not super attractive, or overweight. When we're out places he points out people that aren't dressed fashionably. It bothers me and I usually tell him to stop. I have a particular friend who is a really sweet, harmless guy but he's a nerd and he's kind of socially awkward, and my fiance is always commenting about his "man boobs."
He also is really overly sensitive to criticism and will cry for like hours if someone makes a comment about his weight or points out that he has a gap between his teeth or even just gets frustrated with him. When someone doesn't like him, omg, it's like the world is ending!
My fiance is usually very well-liked in most social situations, and people find him really charming, charismatic, and attractive. One time one of my female friends jokingly said she wanted to marry him and my other friend was like "Get in line, tons of people want to marry him." He is very conventionally attractive and is definitely aware of that. Like I said before, he's kind of always the center of attention and he draws people like a magnet, especially women, which is weird because he's attracted to only men. I've gotten in some pretty aggressive (verbal) spats with women who were flirting with him.
He always thinks people are jealous of him and seems to enjoy that sentiment.
So, even with all that said, I really don't think my fiance is a bad person!
He can be really nasty toward some other people sometimes, which I realize is a flaw and I don't like it, but he is always super sweet and affectionate to me and super protective of me, and I love him more than anything and I do want to spend the rest of my life with him. He was able to overlook my stutter and speech impediment and my C-PTSD and all my medical issues and he truly seems to love me for who I am.
If he does have narcissistic personality disorder, is there anything that can be done to help him? I don't want him to hurt people
I love him and I don't know what to do
