SA, you can do anything you want. You can tell him you love him and beg him to come back but that hasn't worked for you before and it probably won't work now.
This is a very hard place to be and I, too, know how hard the weekends are, especially Sundays. For some reason that's the most difficult for me but it's better know, after almost 2 years it's better.
"How long do I have to wait?" Depends on what you're waiting for. My H also decided he was done, left (no OW) and gives no indication that he even thinks about coming back. He is friendly and helpful when I need to interact with him but never talks about the R or anything that might involve emotion.
Your husband does stop by. Are the interactions pleasant?
I've decided not to spend my life waiting for H to come back but to instead create a new life that doesn't include him.
And this really isn't a game. As much as we (the LBS) dislike what our S's choices have done to us, this is about allowing another to live their life. It's about us becoming better people. Sometimes marriages are saved, sometimes not but if you work the program you will change in many ways.
Hope to hear more from you soon.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
