Pandora, does he know why you need him to come to you this time? If you havent told him everything you've told us then it's very possible he doesnt realize it's not a battle of wills. Men especially, and the workaholic types in particular, can be incredibly thick-headed about picking up on undercurrents in a relationship. If he's not the sensitive-type you may have to spell it out for him...not just drop the ball in his court, but bounce it off his head. Then it's clearly up to him at that point.

However, is his work something which will always be so consuming? Or is it something that will let up after awhile? (ie after a promotion, after a certain time period, etc). Cus I hardly see my husband during his busy season throughout Winter/Spring, but I suck it up cus I know things will return to "normal" come May/June. That makes it a lot more bearable. But if his chosen career is something that will always keep him busy year round ad infinitum, and you have a greater need for attention than that (as is obvious), then there's just no way to make that work. If that is the case, he just plain doesnt have time for a f/t sub or girlfriend of any kind and you're not a p/t kind of girl. You'll always feel jipped and he'll always feel nagged. Not exactly a solid foundation. But if he wont always be so busy in the future, then really it's up to you to decide if you can wait patiently for him or not.
