Ending (spoiler)

That's what i cam here to talk about.

I actually was trying to call it in the final seconds,

Whose at the door,

Young girl
his wife
ambiguous

I likes that the director went ambiguous to screw with you, and minutes earlier he had the conversation with Dreyfuss, who basically said "i want to talk about your hooker issue." gives him a ton of money, then also says to get clean, but ease your way into it.

"I wouldn't worry too much about Ethics reform right now."

So , does he still have the issue and he's gotten craftier. Has he straightened up.

Didn't they say in the limo, that his wife was out of town??

I think he's come to terms with that once a cheater always a cheater kinda thing & basically that he has an addiction - removing his wedding ring makes no difference anymore as he continues with his infidelity and i guess he's become accustomed to his actions. Not to mention that his marriage is already broken.

I dont know if i explained it good enough hahah. But that's my interpretation lol. I also agree, it's ambiguous so i guess it's up to the viewer :)

I thought he was seeing another hooker at the end. The funny thing about the ring was that why did he ever take it off to begin with? Hookers don't care if a guy is married in fact probably prefer a married guy since he will be more discrete and may be less likely to carry STD's.

He killed sixteen Czechoslovakians. Guy was an interior decorator.

He didn't kiss his ring, he wet his finger to make removing his ring easier as he had done every time he met with an escort. Removing the ring wasn't for the escort's benefit but for him to mentally remove himself from being married, so he could be someone else. At the end he was clearly visiting another escort, but chose to leave the ring on because he had now made peace with himself that "he was the guy who would walk through the door". The distinction between who he is and who he had to be to sleep with these women was no longer necessary.

He was a sex addict. He had several close calls. The first one was when he went to the doctors because he thought he might of had an std but that didn't scare him enough. The second time was almost being found out about through the FBI and being publicly humiliated not to mention his wife finding out should of been enough. The third time might cost him and might be 3 strikes and he's out. He's a sex addict plain and simple and doesn't help he's still married and screwing escorts. He's also human but if he doesn't want to change then he won't but it will only hurt him in the end!
