This is likely because her reaction and what you were hearing made you back burner and feel unneeded. This is normal and makes a lot of sense.i was trying to be supportive, but hearing all the noises coming out of that room I couldn’t do it, i has really beat me down, from that moment i understood that my marriage will not be the same, it was a mistake, that i ve made
You already have a bit of luck - She was honest and direct and communicated with you.
You tried it out. You were supportive. But, in experiencing it, the REALITY of it hit. That makes sense. Return the favor and be honest with her.
It doesn't mean things won't be the same. It's just an Event In Your Life Time. Something that happened. It means that this event is now a part of your life and must be addressed. It cannot be ignored.
There may be ugly things that come out of addressing it. Hard realities and serious examinations of who and what we are as humans.
There may be good things that come out of it. I have NO IDEA what will come of it... I know that the ones on this forum that are immersed in the fantasy enough will just repeat "Go for it" without regard as to whether or not it is Right For YOU.
Only you can determine that.
But try not to jump to conclusions, think angry thoughts or make any accusations. They Simply Will Not Help. At all.
And she DID come forward and openly approach you. That's awesome, even if it isn't what you want her to do... That kind of openness is very hard to find.
She may not want to stop Or She may get upset that you agreed, then backed out. Try to remain understanding of how that feels for her.
Good luck man. I feel your pain.
