Losing interest??..4 years in...?

I am 26, Ive been with my boyfriend for about 3.5 years. He just turned 30. The first 2 years of our relationship were VERY rocky. Lots of fighting, arguing, jealousy, breaking up and making up. it was not healthy. We have come a very long way in the past year or more. I am surprised we made it this far. we have both overcome trust issues which was huge. it feels like we have really grown up a lot from where we started. we now rarely argue and have since moved in together, gotten a dog, etc. I am happy to have everything going well. but what really makes me sad it that it when i look back it feels like we completely missed out on the beginning erfly stages. I mean sure there were those anxious fun dates, first getting to know one another...but 6 months into our relationship **** hit the fan. we struggled and hurt each other pretty badly. its all in the past but i really feel like something is missing. It feels sad to not be able to look back and remember being gaga for one another...because although we did and do love one another, it just feels odd. and now that we have been together for so long...it feels like we are very comfortable (which can be good)...and he is good to me...but i rarely feel like I wow him or like he wows me....and i cant even look back and remember barely any of the erfly stages because they were few and far between. i really do love him now....but i dont feel like we have ever been infatuated with one another...and i want more...i want more lovey dovey-ness...i want those erfly stages back...i have recently in the past couple weeks become more withdrawn...went to my moms for the weekend, went to the movies alone...bought myself flowers...i dont know what to do to make him see that I am looking for more....he knows i wish he was more romantic...he rarely tries except on holidays...its not necessarily romance...more just the bond and affection that i want to see more of. 2 of my previous boyfriends couldnt get enough of me...and i dated them for 1-2 years. i guess i want to put him on edge a little bit...make him work for this? any suggestions?
