Hi.
I'm ok. Trying to take it one day at a time.
On the whole I feel positive. I'm happy I've made the right decision to try and work through this. Definitely feel that DH and I are both on the same page as far as that is concerned.
I'm happy that I've chosen to do this for the right reasons, and not through fear or just for the children. I believe that DH is too, although the fear that he doesn't really love me rears its ugly head fairly often and it makes me feel panicky.
He struggles to say it. He comes from a family where they all struggle to say it. (We had a conversation the other day where he realised that his mum has never told him she loves him since he's been old enough to remember.) He isn't struggling to show it though, in the way he's treating me and the way he has changed his behaviour. I need to try and accept that at face value and not expect grand gestures and constant 'I love yous'. He has never been that way. And I fell in love with him knowing that. He balances me out as I'm hugely over emotional.
I think part of the reason I'm generally feeling OK is that DH is trying so hard to repair things.
He's had a long good look at himself and has come to several conclusions about why he has behaved like this.
None of them paint him in a good light. But he's been honest about how stupid he has been.
I don't want to go into them on here, because I'm pretty sure someone will come along and try to say they should be deeper or that they can't possibly be the reasons. I'm 'happy' to accept them, even though they anger me and make me feel very sad.
He has not blamed me for a single tiny thing. And I don't blame myself either. I blame him for it all.
I'm trying to move forward. It's hard. There are setbacks. There are moments when I think of something new to ask him about what happened. Or moments when I have a flash back of some sort to the evening when I found those texts. I feel upset frequently. And angry occasionally.
I feel anger towards her too. I feel entitled to do that, although I know there are many on here who would say I shouldn't. She is married and as culpable as my DH. It annoys me that her relationship isn't suffering and I feel sorry for her husband that he doesn't know what she's done to him. But then I also wouldn't wish what I'm going through on him. And I don't care if she's hurting from what DH has done to her.
DH hates himself for hurting me. He is angry that he did what he did. If he could go back and change things he would. He can't, I can't. If only we could!
So basically - trying to move forward. It is still very early days. It feels like the longest 3 months of my life! I did have a moment today when I suddenly realised I hadn't thought about her for an entire morning! That was nice!
Thanks to everyone on here who has supported me, and posted on my thread, even if I didn't seem to take on what you said on board at the time. I was so hurt and dazed initially - I honestly thought I wouldn't survive but you were all amazing.
And quite honestly, I think I'm pretty amazing too! 
Nest of vipers, eh?
