Just de lurking to say I am following this thread as my H had a 5 months affair after 14 years together. I am two months on from finding out (27 September), we didn't separate due to the kids but I think that was a good idea in our case as he got to experience first hand all my emotional rollercoaster. I asked him to leave several times but as he's truly remorseful and we are in marriage counselling I've changed my mind each time.
He knows there's no guarantee I'll stay and each beginning of the month he has to check if I am still willing to continue. My marriage counsellor told me that when I am feeling dispair I need to remember the decision is mine, and not making a decision yet is still a decision.
All I wanted to say is hang in there it will get better. The pain will fade slowly and you'll end up numb for a while. That's the stage I am at now. I look at him and don't feel much, we have sex, amazing sex but no emotional connection on my side.
We talk about it everyday for hours, we've been through really tough times on both sides, my H sobbing, trying to hurt himself when I tell him I cannot do it anymore, both been suicidal at times...
Anyway there is an American forum (with people from all over the world) called surviving infidelity where you can understand more by reading the posts if your H is doing the genuine work or not, you can see you are not the only one going through it and feel a bit more knowledgeable.
I wanted to make this short but I am not successful, all you are going through I am also or I have been there already.
I am numb and I am still not sure this will work out, some days I am positive, some days I want to call it a day.
Stay strong all.
