Juju - I don't accept that it's a given that the "in love" feelings have to fade after a couple of years. I know they do for many people but they never did for me - or even really for my ex. Sure, he dumped me after 26 years and he had issues with faithfullness but really our relationship never suffered from lack of passion until he made his decision to leave.
If this guy is a good match for you - which he seems to be - and he doesn't have a history of falling "out of love" every coupe of years, I think things will be fine. Two grown adults who know how to treat their partners and have healthy boundaries should do great.
