It's interesting. So often the problem couples have is that they only have sort of casual unscheduled time, and they don't have any "Date nights" - it sounds like you have date nights, but you long for the casual unscheduled time together.

So what you need to do is make some standing "date" nights, even if you're not doing anything. "Hey, every Wednesday night we just hang out together and don't work and don't do video games. We cook together and watch a movie together or read together etc and it's not a replacement for going out and planning an actual date night, which you do and I appreciate."

And you also have a little flexibility, so that, say, if he's on a deadline you miss one week that's okay, or if he wants to change wednesday to thursday (and gives you adequate notice) that's okay, but you make a point of scheduling some "unscheduled" time together every week.

And then what you do is start filling the time on the other nights of the week, so you're not waiting for him. Maybe you start a regular thursday drinks or dinner night with your girlfriends. Maybe you pick up a new hobby. The point is - you allow the fact that you know when your "unscheduled" time is going to be with him free you up, so you're not waiting for him the rest of the time. ("I know he won't be home early on Thursday, so i'm going to go do something else.")

Try to frame this for him as a positive: "If we have this once-a-week time together with no big plans, that will mean I pressure you less for your attention the rest of the time."
