I'm going to sleep with my neighbor's wife
You can't go through with this. Why would you sleep with her?
I think she is interested in other people
You should not act on your feelings of sleeping with someone else's wife. You will cause so many problems and destroy multiple families if you carry through.
The neighbor wants me to sleep with her
I believe you shouldn't give into her temptations, it will only end badly for you since she is married. How about just ignoring her, or notifying her husband of what she is doing? He doesn't deserve all this betrayal behind his back and deserves better.
