Update*

After talking to my friend he told me that he talked to his wife and apparently she shot him down and said if there was anything sexting or exchanging photos etc she would consider that cheating. Then i wondered if it had to do with the fact that she may not feel included (keep in mind she has no idea of me). well it didnt matter cause she was still not down. then i wondered if it was becuase of jealousy, apparently it wasnt that but becuase how she views marriage. So im wondering if my concersatiom and reponse were good enough to spark another conversation between the two but honeslty i am not holding onto hope with this one. he said he values respect as do i and for a marriage to go haywire becuase of a fantasy is stupid. so ill just accept it and move on. Frienship after this is unclear only cause i feel like i was in the wrong and i put him in a eery predicament.
