what's the use

Again, caught in a lie. We live in Vegas, the capital of strip clubs, yet he decides to got out of town for work and lie about going to a strip club. Why? I've even taken him for a lap dance, no problem, because it was between us. 
So???? why lie about it??? Does he get off on thinking he's getting away with lying? is he obsessed with strip clubs? Or why? I don't get it. Why not be honest with me and avoid the consequence of having to lie? We'll that's just it. Every time he lies, I forgive. He knows this. So far the only consequence has been fight, silent treatment for a couple of days, then make up. Is this why ? for the making up part? 
I don't know!!!!!! I don't know him anymore...... 
He's got beautiful brown eyes. I used to look into his eyes and just melt. But now, all I can think of is, "what are his eyes telling me? is he looking away? is he telling the truth? is he lying?" 
I certainly can't trust what comes out of his mouth. When he says I LOVE YOU, i don't even absorb it fully, always thinking it's a 50/50 chance that he may be lying. 
I wish I knew why? I don't even think he knows why. Why? cause so far it's worked for him. 
I can't keep doing this. I'm soooo tired of the lies. Soooo tired of not being valued enough to deserve the truth. Makes me feel worthless. So, why stay together?
