Welcome to pherotalk Stephanie,
We all know that the way things once were could never be in terms of how it started but there are many relationships where the passion and romance never died and is still going.
I am sure he still feels that way about you so he just need a reminder as you said and lets see if sexiness, honesty will do the trick.
You also want to play your part by making or bringing him an environment where he can be relaxed and you guys can spend some time together that is romantic and inviting.
Maybe do something crazy like rent a motel and ask him to meet you there or find a way to get him there
Be creative to get your guy to remember those good times.
