Sounds as tho you had a great week-end with NG. It's his behavior that counts...I have to keep reminding myself of that as well. My H doesn't bring up our R at all, but continues to make plans....Oct, Nov and Dec....with me, friends and family. That is big.
Try your hardest to be strong on your get-away to your holiday home....don't let the memories sabotage you....just enjoy. (Easy for me to say, I know)
Just want you to know, that I'm thinking of you...and noting all your steps in a pos direction. About the cell ph #....my H kept OW's on his for a while too....really bugged me.....but even looking at it was wrong of me, I know. Then, I finally looked again...when he got his new phone about a month ago....and it wasn't there. He didn't re-program it in. Now....no more snooping for Mooka....
Just have to remind myself to let it go....the past is the past.....pay attention to the NOW and keep letting those baby steps build day by day.
