Hi all.  My one year d-day "anniversary" is in a few weeks.  I posted in JFO a few times in the immediate aftermath and got much support from the wonderful folks here.  Since then, while I haven’t posted, I have lurked and have learned SO much from everyone’s experiences and advice.  Thanks to everyone who posts their questions and to all who answer and provide much-needed support.
I consider us to be in R but know that if things get too painful, I can and will walk away - and he knows that too.  I am extremely fortunate (?) that while my WH cheated, he pretty much immediately admitted it when I found out and confronted him.  There was really no TT and since day one he has been a "model" WS (broke it off with and cut off all contact with his AP, immediately got into IC, is always willing to talk with me and listen when I need to in spite of it being uncomfortable for him, having totally open and honest conversations, doing little things throughout the day to show that I and our relationship are a priority for him, showing real remorse, telling me how much I mean to him, gave me access to all his devices, etc., etc.).  However, and I know from reading here that this is normal, I am really struggling as the one year mark approaches.  I still lapse into wondering how he could have done this, why he couldn’t be the husband he is now without the betrayal, etc.  I have had my moments over the past year but it feels particularly acute now.  He understands ( he has done a TON of reading about infidelity, how to help me recover from it, and done a lot of work to figure out how he got to the point where he cheated) and is trying to do what he can to make it less painful for me.  
I guess I’m just looking for suggestions on how best to get through this period, although I suppose it’s no different than what I have been doing - accepting my feelings, allowing myself to feel the emotions, and then discussing them with him after I’ve processed them.  But if anyone has any other suggestions, I would love to hear them.
Infidelity just really, really sucks.
