It seems like you need a way to keep the flame of love burning brightly without spending much time together. Perhaps treating it like a long distance love and using love letters by email would be a way to go. You could get into regular correspondence and talk about the things that matter most to you, and he could do the same. And you could set aside a single segment of your week-=-or every 2 or 4 weeks, to see each other. For relationship research has found that Long Distance relationships in which the lovers meet once a month or so can stay burning brightly for many months or even several years. And that's how people keep their love relationships in a very small cubicle amid a very busy work life. One of my old friends had a 7 year LD before his GF retired as professor and then they married and moved together.
