I need some ideas how to bring back the spark in our marriage.

me and my hubby work together and we been together for 5 years so after working together for 3 years and being so busy we hardly take time to enjoy *us* or go on dates ect and we're ttc for 2 years now. idk how I should tell him that I would like for him to still ask me out and stuff just be romantic lol like he was when we started dating. I would love to hear some ideas. thanks!
