We could write a whole album! Love songs for housework!

I love cleaning with music on too, but I do it alone.

I think you hit on the crux of the question in your last line here. Love someone as hard as you can, but love others too. When the object of your love becomes the only thing in the universe, it gives that person too much power and the tunnel vision is blinding. It's not that you love too much, it's that the love is concentrated on too small a sample.
