Not Engaging

Hi

I am trying to not engage with my Narc husband when I know he is lying or sneaking as it gets me nowhere. However, after I not engage/"take the bait" by walking away or hanging up how do I stop thinking about it? I get so angry about him lying and sneaking and it seems to me that by not engaging he is just getting away with what he wants to do but now with no hassle/accountability (by me not engaging) whatsoever.

Like today, we were on the phone and he brought up the fact that he put in an application online and about 10 trucking companies called him about it (he is a commercial driver). Then he said, "one just called me now". Then he tried rushing me off the phone by saying "you have to hang up right? You are really busy, right"? I never brought up the topic of if I was busy or not. HE just wanted me off the phone to call back whoever just called him (and I don't believe it was a head hunter from a trucking company -- as he has told me too many times in the past that he doesn't call them back right away. That he waits to see if they leave a voice message and what that message says). So why all of a sudden does he have to hang up for a head hunter? No, no buying it. But, rather than say any of this I just told him I had to go and hung up. But now I have been sitting here thinking about how he ran me off the phone and he thinks I don't know what's going on and it pisses me off. I know that saying anything about this to him would just get me another story/lie, but other than that, I don't see how it helps me? I just sit and stew about it........
