*sigh*... ok, this is how you might get it out there...

"W, I was at my IC the other day and the IC said to me... 'SP, you might want to share your feelings with your W.' So, W... I felt I wanted to share now...

I understand how you could be feeling [this way (insert something that you understand how she could be feeling)]. Myself, I feel that while it may not be obvious all that I do around here, I feel that my contribution to this household and family is either unnoticed or unappreciated.
"

There... that's it... nothing more... put it out there, walk away... no expectations... if your W offers feedback, just listen... validate if appropriate... speak of it... no more... even if she asks you to elaborate... the whole "putting yourself out there" sets you up to be baited and trapped into engaging in something that your W is likely speak on, which could likely take the convo down a painful, and pursuit like convo...

Very anti DB... no R talks... and convo about how you feel under appreciated... well... it's an R talk...

Your description of your W's reaction to "R talk" is very important... she has told you... she doesn't want to go there... so understand... if you go there... it could get ugly...

Your last paragraph ^^^^^^^^^^^^ read it again and again... remember it... have it tattooed to the inside of your eye lids...

Keep working on you and be the best man you can be, that only a fool would leave... and the more time you have to do that... really... the better...
