Unable to overcome the neighbor's temptation

I left my wife and children in my hometown and I'm working alone. When I was starting to get used to this life, a young woman moved in next door. She used to be an active preschool teacher, so the distance is shortened when she consults with her son who lives far away. Even though I knew it wasn't good, I started to think of her as a woman. As if realizing that, she invited me as she spoke. I'm jealous of your wife that such a kind person is her husband.
