I know how hard it is to sit back and wait and see if someone does something you want, believe me been living it now for 4 years. I know how tempting it becomes to want to bring it up again, to want to ask "ok you know what it is I want/need...so why aren't you doing it?"
I also understand the frustration that builds up sexually when there is no release for it. The way I see it is....if it gets to that point stop drawing a line in the sand and erasing it with your foot. Enforce it for good. Honestly, putting things off until the kids are out of school and she's out of school...is generous of you but there is nothing that says you cannot change things if you reach that breaking point. GEL
