Wow T2, You certainly have come a long way!!...I want to thank you for visiting my thread and the wonderful advice you have provided. You are an inspiration to us all. Regarding your post above, even though W and I are still S, one of the fears I have is exactly what you expressed. And I don't know who would be leaving who behind. I feel as though I am committed much more to the R since she is the one who decided to walk. But if we ever do get back on track, I kind of identify with your feelings about the WAS "catching up" and if she doesn't, perhaps I really don't want to salvage the M. (Boy, I never thought I would say that!) I guess it is just the harsh reality of the sitch.
The only thing I would suggest to you is to not keep your expectations for your H a secret. That's how many of the LBS wind up here in the first place. Perhaps you could share this with H in a counseling session so H doesn't perceive it as a threat.
Most importantly, live one day at a time...Don't project what you think is going to happen in the future. Making your M work "just for today" is a much easier goal than worrying about "making it work forever". Enjoy it in little bites and savor even the smallest, little morsels.
I wish you continued success and I will check back often to see how you are doing.
