In a side note this part of your signature looks silly:
"agreed" to "working on r" Mar 3/13
I highly doubt in my opinion he came to you and said that . It sounds like more that you pressured him and he gave you the answer you wanted to hear so your feelings didn't get hurt
Why don't you put that up there when your H truly comes to you asking to get back together and work on things . I don't think he will until you take the advice on this board.
The stuff you posted above are some good starting points.
But you need to let go of your husband , give up control, and work on yourself. When you interact with him for business treat him as peer and that's it.
Don't analyze txts, txt response times, etc etc etc. just stop. Put a rubber band on your arm and when you want to obsess about H , snap it hard. I use to visualize stop sign or pull my arm hair .
You can do this.
