A big FU

The lies just keep piling up. Several months ago the Narc told me he left his wife and was living with his dad. Narc's hometown is about 45 minutes away from me. Anyway, I suspected he was lying, but really had no way to confirm. At this point in our "relationship" I had already told him, after a 3-month ST, that I had no intention anymore of leaving my husband and that the only thing we had was a friendship. So, because of that, I couldn't figure out his end-game as to why he would lie about leaving his wife. But, since it really didn't matter, I kind of chalked it up to his being a Narc and let it go. Today, I discovered that not only did he not leave his wife, but that they, as a family, went to Disney World twice during that time, and it looks like they bought a timeshare there. I am so pissed off right now and I really can't figure out why. I've been NC for more than 2 months, and have completely blocked him, and have absolutely no desire to contact him and open that ugly can of worms. But, I so wish to just scream at him and say FU, I knew all along you were lying. I think the thing that infuriates me the most is that he probably thinks I'm stupid and gullible for believing all the lies he told me, when in fact, I did not. I just let my love for him overshadow everything logical.
But, I know, thanks to all of you, that the best FU is silence on my part. I just hope he hears it loud and clear.
Thanks for letting me vent.
