When does it end

So, I found out my wife cheated on me about a month and a half ago. found out because while we were on vacation, she got a text message after midnight so I checked her phone (our kids were being watched so I figured it would be somethin from them). What I saw was messages from a number saying he was horny and askin if she was out with their 3-some. I responded to the text askin what they wanted and received a reply of 2 pics of his...junk. When I confronted her, she said it was her nephew's number. The story didn't jive so I dug further and found out who it was. When I did, she said it was a one time thing and all that happened was a kiss. When I dug further (called and texted the guy) he finally responded that he was sorry and didn't know she was married. When I confronted her on this, she owned up and said it was a one time thing and they met that night through a friend. When I dug further, I found out he was a golf member at the country club she works at (doing the beer cart girl gig). When I confronted her, she admitted it but still stuck to the story. When I went through her past messages, I found a message to him from April (it supposedly happened in June and we got the text of his junk in August). She has also lied about where she has been while working there and blew me off several months ago and when I went to her work, she had left to go to a different bar with another guy, albeit her boss...who has had an affair with another female employee there.

So, we are back together but she REFUSES to leave the job at the country club saying that I can trust her now and nothing is going on.
My question is, is there ANYONE out there who would allow this to continue?

Keep in mind, we have two kids so a split is not much of an option...I lose her and the kids.

What can I do? What would you do?
Am I crazy?
