<human>: [OP](

I got a little nervous that she was cheating on me after reading everyone's responses but it turns out it is just a fetish thing. I found that out by playing along with her little game of "try not to cheat on me today" and said I couldn't make any promises and you can imagine how it went from there. 

The thing is that I'm not into the fetish at all and don't want to entertain it. I've told her she can think about it or whatever but I don't want to be a part of it, and she's not really easing up on it. It seems like she thinks in her head that she can keep annoying me with it which will push me away and make me cheat on her. Is divorce the only answer? I hate that I'm even considering it but I don't know what else to do. I don't want to tell her she needs therapy because she has a fetish that isn't even that weird but I really just want nothing to do with it.

Can you condense the text into a few key points?
<bot>: my wife has the female equivalent of a cuckold fetish and doesn't seem to mind that it's driving me away because she thinks either way I'll cheat on her.
