Yes, and very simply. First, you're talking about romantic partner love, not human love for family or things. Any system needs fuel. If both parties are in love, and apply effort - a state of love is achieved. The system of love is sufficiently supplied. It is only within this state of love that the state of love itself can be improved and refined, which takes equal effort from both parts. Within this system, acts of selfless love can be performed for the partner, whether it's a foot rub, doing the dishes, going on vacay, taking care of them when they are sick, telling them pleasantries, giving them multiple orgasms even though you only get one....... This is love. Small scale, moment to moment, daily love IS the "ultimate love" you speak of, because this is where it is built. It isn't until the end of the road that you can look back at the monument you have created in tandem that you will truly understand the power and the meaning of love. Until then, you believe and hope, and that's what makes it happen - that's when it finds you. If one person is not trying, it is not love. But if both try, it is achieved. It is not uncommon.
