dating after the narc

I was wondering how best to deal with the nagging doubts in a new relationship....the new man in my life has been nothing but wonderful (and I am thinking...he's to perfect - red flag) he does the right things, reacts just like I would like him to every time...and yes, I do find myself "testing"...not proud of it but I just find myself red flagging the tiniest things out of fear that I am repeating a pattern here and confronting him about it....if he is just another narc and I am simply in the love bombing phase can I do anything else but wait and see until the mask comes off? If he is the real deal, how unfair am I to him... maybe even to the point where this relationship doesn't stand a chance...? I would really like to know if any of you have any insides into dating after the narc?
