I understand what you mean about cutting down the time on this site. With the best intentions, it is easy to sit on here for hours, without going out into that big bad world.
You are at a place where I was a short while ago, I was ready to move on (or so I told myself), but then the W started to change (in reaction to my changes?). I can see that from your posts that you want to get off the rollercoaster, but....you are there for your D's.
It is the hard season to feel like this, but please realise that you have also been a beacon of strength for lots of people here (me included); we would miss you.
I am like you and H4C, one night stands are not for me; I will always want the stability of a long-term relationship. If it doesn't work out with your W, lick your wounds, love your D's and in time you will meet the girl to blow you away; and 40 is no age ;).
