If you mean kind some kind of romantic love, my own experience isn't the same as yours. You said ...
love is non hate, non greed, and (hopefully) non delusional
... but I'm not sure I agree:
- "non-hate" -- if the 'love' is the result of (i.e. conditioned by, conditional on) experience[s] that you like, then when the experience ends the love-you-experience becomes aversion-you-experience.
- "non delusional" -- to the extent that "identity view" (of self) is a delusion then love might be a similar type of delusion (e.g. seeing the object of your love as a person who has/is a fixed identity)
In summary I suspect that love is "attachment".
There's a book I mentioned in this answer titled The Buddha's Teachings to Laypeople: Practical Advice for Prosperity and Lasting Happiness. It says that most of the suttas were written by and for monks, but that some of the Buddha's advice was for people in lay society, and it summarizes some of that advice.
In my limited experience the good side/aspect of love might be right/moral/ethical actions and views.
In retrospect (i.e. looking back) there was a time in my life when I was motivated by (i.e. when my love was expressed as) wanting to be kind and to do the right thing.
It's these "ethical" actions that I don't regret -- which is inline with the Buddhist suttas, for example the Kimattha Sutta:
Skillful virtues have freedom from remorse as their purpose, Ananda, and freedom from remorse as their reward
It might be worth also considering the doctrines about admirable friendship. The various doctrines (e.g. "Keeping company with the wise" and "Never with an evil companion") suggest that the benefit is conditional on who you love -- i.e. not just on the nature of your love but on the nature of your beloved.
"The whole of the holy life" is I suppose (in context) about the benefit of the monastic sangha; perhaps if you're lucky or wise or both then you might experience something like that in a lay relationship.
