Living with partner of 7 years who gets a new job which causes great negative changes to the relationship. A difficult time, but while I'm trying to accept it (and when we're actually together, things are fine as usual), he's trying out an old friend as a new gf. So at the first sign of difficulty /disagreement, he's bailed on the relationship behind my back. Is this a classic narc move, or just plain selfishness and immaturity? He did 'come to his senses' and ditch the bitch, has now showed remorse etc, but something I read on narcs has made me wonder...
