I agree with you that we should hold a contest to see who is the Queen of Backslide here! You know by now I am also in that category. But having said that, it is ironic that everytime we backslid, we'll get better at our DBing, we have new strength and new wisdom.
I look at your sitch and I was thinking, at least you have H at home with you (or is it? Or I thought so?)! Not that I say it's easier or anything, as I believe that every sitch is unique and has its own challenges. But I'll do anything to have H with me at home.
My H is living with OW, and every waking moment that I have, I cant help but visualize that H is with her when he is not with me, which is almost 7 days a week. he calls me but he calls OW more, and he is saying that he will be home soon! I just read DR again and this time it gets to me when Michelle said that focus on problem free times and enjoy that moment. I;m trying to do that and I hope you will too.
I know its difficult when your H seems to be testing you. My H also is scrutinizing my every move, which is killing me, and every time I seemed to say or do the worng thing, he will drill me on it. Feels like I am walking on eggshell nowadays.
There's a thread called its not too late here, cant remember the poster, but she gave me hope. Go check her out if you havent.
Take care...
