I know I should let it go, but I want to simply say to H that it seems he doesn't want to go out Sat night and that's fine w/me.
Here's another idea to take the "pressure" off your H - suggest doing something fun with the kids on Sat. night. Then you aren't pointing out to him that he doesn't seem to want to go out which is probably something he feels bad about.
I know my H has no problem and even enjoys doing things as a family, but many times seems uncomfortable when we are alone together.
An example from my life: last week our friends offered to have both D and S over for a sleepover because they have a D and S the same ages. I asked the kids and they both wanted to so I said yes. Then I just got the feeling that H would not look forward to having the house just to ourselves for the night (we used to long for those opportunities! ) So after I hung up the phone with our friends, I suggested that we have the boys stay at our house and the girls could stay at the friends house, and I said I'd call them back the next day and suggest it. I figured if H did want to have some alone time with me, he could say "no, let them all stay over there so we can go out", but there was no pressure at all from me. It turns out he didn't say that and the boys did stay at our house. Since I have no expectations (even though I would have loved a date with my H or a quiet night home alone with him), I was fine with it and it was great.
