How can I make things sizzle with my Aquarius man?

Im a scorpio Nov 8th and my man is an aquarius Feb 17th. He thinks our relationship is going well but for me its just ...blah. Its boring but I do care for him. Its just that I dont know how to really get into his head. I try to be extra sweet and it doesnt work. I try to bring up things to talk about and he never likes the topic. I asked him about his day at work lat night and he just said it was fine, period. OMG lol! He knows all my bosses names and every detail of my day and all i get out of him is one word. The only time I see how he really feels about me is when he has the nerve to accuse me of cheating or if he see's guys checking me out. Anytime we plan to go on a date he always asks me if im gonna pay for US. WTF! how can I get what I want. Like a thoughtful , interested in my day , doesnt mind paying for my ticket once in a while type of aquarius. I like him but I need to have some fun. What do aqaurius men like in their women ...how can i make things sizzle?
