This is my very first post in these forums (hi everyone!!) been "lurking" around here for a couple weeks, and your post is the first I've felt really compelled to respond to.
My advice: girl, RUN FOR THE HILLS!
Seriously. What everyone else said here is totally right.
You probably feel strongly about him because NPD folks can be soooooo charming at first. Yeah, they make you feel good...you know what else will make you feel good? Heroin. You know what heroin and narcissists have in common? They both make you feel great one second only to leave you feeling like total hell the next; and they are both addictive in they're own way. As someone who's done both heroin and an NPD boyfriend, I can tell you that the two experiences have some eerie similarities. This man's charm is most likely an illusion, do not be fooled, do not become addicted to him, it will suck you dry!
I was in a relationship with a narcissist for two years. This man completely broke me down and just kind of sucked the life out of me.
Narcissists tend to lack empathy. This man will probably never be able to sympathize with you and give you proper support when you need it. On the contrary, YOU will probably find yourself constantly having to take care of his needs, because in his mind it's all about him. Should you find yourself unable to care for him, and tell him no you can't help him with something, there is a great chance he will respond with anger and "guilt tripping" you. If you're anything like me, you may find yourself feeling worthless and guilty about things which you really shouldn't feel guilty for. When you get involved with someone like this you are putting your happiness, self-esteem and general well being on the line....and NO MAN IS WORTH THAT!!!!!
The good news is, there REALLY ARE some great men out there! Guys who are not narcissists, who will give you the love you truly deserve. These men may be hard to find, but keep digging and stay patient, you'll find him!
I know how much it can suck to be single, but it's still a lot more fun than being in a bad relationship. Don't ever settle for anything less than your dream man.
And most importantly, you need to fall in love with YOURSELF before you can fall in love with another person. It's not always easy, but you can do it
Love and light to you!!
