I've been married for 26 years and we dated two years.
Two years ago I was really close to cheating, she was in a rough relationship with her husband and I was going thru some crap. She is 25 years younger.
She is beautiful and we connected deeply, luckily I was in therapy and the counselor was blunt and told me straight up I'd ruin my life and hers.
I backed off and so did she.
Then as it goes in small towns my wife and her became friendly and she asked my wife if it would be ok if she asked me to talk with her husband who she had tossed out of home.
I met with him and we talked once a week for a month or two and I passed the name of my counselor to him and he got help and they have a great relationship as do my wife and I.
I worked even harder in therapy and am so grateful that I did not act on my natural selfish desire.
Thankful and grateful nothing happened physically.
