Goodasgoldilox - I have felt really numb about it all. i would never ever have thought that he would cheat, however I am not stupid enough to think it couldn't happen. I guess I am feeling numb because I am unsure whether it has happened or not. He has lied to me before, when our youngest DD was a baby, a serious lie which nearly split us up, and he was so devastated and distraught I never would have thought he would risk it again. It didn't involve cheating though (I don't want to go into further details because it would be too identifying). So I am not shocked, I'm not really anything yet but I have started to feel sick when I think about it all.
ToothyMcPuthy Yes the fact they have named the specific person who I had some concerns about (but didn't mention them to DH at all) is a bit of a concern
ElderflowerWaterIsDelish I have no idea who has send the email. The person is, for example "Annie M". There is no one on the "OW" friend's list called Annie, nor my DH, nor other colleagues of his.
Just to clarify, possible OW no longer works at the workplace so turning up unexpectedly wouldn't help me 'catch him out'.
whenyoufeelsotired He wouldn't go through my emails but its a good plan! I don't think he even knows the password to my laptop. Not for any sinister reason, we just use our own stuff.
mikeyssister I will have to find out what this is about. Because i don't feel I can just ignore it. Not that it would eat away at me, more that I am emotionally very guarded and when I feel I might be getting hurt I start to withdraw. Which is probably why some people think I seem cold. And I know this is probably not the healthiest option but I can't really help it.
SleepFreeZone I think this is maybe what has happened. I definitely don't think there was some love affair
TheTapir that sounds awful. I feel the same in terms of him not having time, he works about an hour from home and rarely goes out in the evenings. He doesn't have his own office. Which is why I think, if anything has happened, it would only have been when he was away. But then you were in a similar situation and he managed to have 3 affairs so clearly they can make time if they want to.
Bluntness100 I have really appreciated your input on the thread. The only real 'suspects' are people he works with, or the 'OW', or her friends outside of his work, because of the emailer naming the 'OW' - none of my friends would have named her as they don't know her name. I am certain DH would not try and find a reason to leave, he constantly tells me how much he wants to be with me. He has made some sacrifices in terms of his life decisions so that we are together.
YearOfYouRemember He was due to be back on Saturday. However he has called me to say he is coming back tonight as he is unwell. And big thanks for your support 
PeanutButterLips Yesterday I set up a second FB account to a different email address, so I could have a nosey at 'OW' fb account. Her friends list is hidden, my DH's isn't. DH does not have her on his friends list. She has a picture of her and another man as her cover photo. She would have been single if/when this happened with my DH. Anyone wondering why I did this, the main reason was I thought she had blocked me, turns out she hasn't, but I wasn't sure of her surname and had to go through a few of DHs colleagues to find her. Second reason I did it from a different account was that I didn't want to start suddenly popping up on her 'people you may know'. She also does not have a friend with the name of the email sender.
Hopefully I have replied to everyone...
Brief update, DH is now coming home tonight as he is unwell. So my current plan of action is:
- Look at his IPad tonight when he is asleep and look for evidence. There is no way I can get on his laptop and I am not sure if he has synced his emails to his Ipad, but I will be able to look at his FB at least. I will only be looking for evidence of conversations between him and her, I am not going to snoop through all his private stuff.
- If I find nothing, reply to the email. Suggest this person calls me or at least gives me some more information about how she knows, how many occasions etc.
- Talk to DH. I know for a fact that if I give him any opportunity to find a way out of him telling me, he will take it. So I am thinking of saying "I know what happened with you and X person when you were away". or maybe "This is your option to tell me what happened with you and X before"
I know a lot of people have suggested that I speak to him first, I will never get the truth if he has cheated. I am going to do my own digging and then ask him, I feel its the only way I will get the truth if there's anything to find out.
I feel quite numb about it all and the thought of having to split up, sort the kids, etc is daunting but I will do it if he's cheated on me. Its more the lying I think, I couldn't deal with knowing he had lied for so long. And I bet he wouldn't have been careful so I would then have to go and get tested.
So I will be seeing him tonight and will have to pretend I am all ok and everything is ok, and he will tell me how much he has missed me and wait for me to say the same.
