Back story, I have a dear friend. We originally met in an internet forum 8 years ago. We have chatted many a night or day since. I have chatted regularly with his wife. We have been to their house as a family about 10 times, his wife has stayed here twice for a girls night out, he has stayed here a few times for dinner/work.
So I am friends with them both. I know the inside of their marriage. She will not have sex with him again, she has told me and him that. they haven't been intimate for 6 years.
So now the problem. He stayed here last weekend due to work. We went for dinner as usual drank 4 bottles of wine (still usual) but this time we got intimate, he said he loves me and has for 8 years. I adore him but I don't love him ( i don't think, we are perfect in brain and thought, but he isn't my type and of course am hating myself for doing the deed when I love his wife too!) I told him exactly that
Now he is different on msn/phone. Still there but not there in some way, if that makes sense
I told him, we can't go there ever again, he says we can to return to how we were before
Can we??? Have I fucked up a brilliant friendship?? Should I walk away from dear dear friends??
(I know I'm a complete shit for doing this btw, I don't need telling I shouldn't have done it, but I do love them both as friends and don't want to lose them)
