fwb or nah

I'm in need of advice. I've been single for almost 3 years and finally found someone worth dating. However he had a very hectic schedule and works wayyyyy morn than I do. Sometimes I see him once a week and wasn't enough so now every other day we spend the night at of our houses. I wanna go out on dates, to movies, have fun etc all we do is barely make time for sex. Should I give up and move on or wait it out. I've told him this numerous times and he says he's going to change or working on it and now I'm officially sick of his shit! Opinions?
