Straight to the point, she lied her ass off, literally. She told him she was working at some store, but was working in a brothel? Not only is that lie sorta up there among the big ones that your significant other should be aware of, but exactly what else would she be lieing about?
This isn't her having some problem with gambling her money, this is her going off to a brothel to treat other men besides her husband, whether that's putting on a show, or putting themselves ontop of them (I didn't see many details)
If you want to have an open sexual life while married or dating, fine... but make sure you tell your partner and make sure they're cool about it, don't hide it behind their back. If they're not cool with it, then you're not with the right person. Even if you're not having sex and just flashing your body for money, it's the same principle.
I have had my ex's freak over myself exposing PG-13 body parts to other friends as a joke, let alone sexually.... if I was doing it behind their backs and in a sexual manner, I imagine things would have been even worse.
How would you enjoy seeing your husband or boyfriend up on stage gyrating their crotches at the ladies in front row and they're screaming and grabbing at them and he's all smiles and sunshine for it.... and getting paid for it too.
Those are other women touching your man behind your back... he didn't tell you about this. Who knows how long he's been doing it. The Situation changes all of a sudden doesn't it? You get a little pissed off about the lies and the fact that these girls may actually be getting more attention then you are at home. Not to mention, when was the last time he ever stripped for you?
That's right, time to get a little PO'd and grab a lamp for a weapon.
And about the details on him going there and finding her and why was he there in the first place:
They didn't really explain why he was there, but if he was a regular person to these things, I would expect he would have seen his wife sooner. I'd have to say a friend of his might have suggested that he go to this paticular place at a paticular time, which is common for friends to do when they see their skank girlfriends screw their friends over.
I mean I've got quite the open mind to just about everything, and if someone I am dating wants to try something, or has an interest in something, so long as they talk to me about it first, I can look at it from their perspective. But if they can't feel they can come and talk to me about something like this, then I'm not who they want in the first place because they don't trust my abilities to relate to their desires. If they don't want to give me that chance, screw them..... literally, someone else can screw them
