Which I do not know how to fix.
So one of my good friends(was the first friend i made when i moved ten years ago) works as a pilot in the air force(Australian). Well to cut a ,longish story short, i got a phone call from him last week(he is deployed at them moment(4 months in) to swing by his house as his partner was wife to him that their shower was leaking. So after his call i head round there the first chance i can get after work to help him out.
So after i find the leak and seal it up it is getting pretty late and she has made dinner as a thank you. She also doesn't know I am a former alcoholic and been sober for four years, she offers me a drink of red wine which i just accept because i cannot really be bothered explaining my pathetic past to her.
Well one drink leads to many and the next thing i know we are in bed together going at it. After that i do not remember much but waking sometime after 2am and getting the fuck out of there.
Well i get a call the next day from my friend thanking me for fixing the shower and to my relief he has no idea at the moment.
Now i normally have no problem cheating with people(that is their wives problem not mine), but this broke one of my golden rules of never sleep with anyone i know for the risk of ruining my relationship with them.
Well i know it was a mistake and wrong but i have no problem with guilt(never felt any for anything ever) so for me personally i could go the rest of my life without feeling the need to share it and carry on as normal with the friendship but what do i do about his wife, for all i know she could be planning to tell him, she might not be able to handle the guilt. For all i know she could have done this multiple times and is screwing him over.
So what should i do. My thoughts so far have been.
1. Don't tell him, carry on and hope she can shut her mouth too.
2. Tell him the truth and end the friendship and his marriage
3. Tell him that she got me drunk, seduced me to sleep with her then tried to blackmail me(he knows my past, and this will make me a victim and might be able to keep friendship, more of a preemptive strike) and end his marriage
4.Call her and talk to her to see what she plans on doing(this seems it will be too awkward)
5. Block his number move house and never talk to him again just in case he finds out
6.something better? if it even exists
I acknowledge i have done a terrible thing but i just want to know what is the best way to fix it(or just ignored it) and try and remain friends
This happened at the start of the week
