But H has maintained open communication and has said he will calmly and truthfully answer any and all questions I have, if any should arise, for as long as I have them.
I think this part is key. ^^^ Whether or not the betrayed spouse ever feels the need to take them up on it, I think it's important that the formerly wayward spouse to commit to this.
And for their part, the betrayed spouse needs to commit to not freaking out when they get their answers, and to say "thank you for being honest with me" even when it's extremely painful. And most importantly, to NOT LORD IT OVER THEM for the rest of your marriage!!!
