I have to agree with Meagan and Arwen.
Ultimately, one does love their children more than a spouse (at least, I love my children more than any partner I have ever had). It is an unconditional love that does not require the other party to return anything. My children could do anything (ANYTHING) and I would still love them--I might not understand it, I might not condone it, but nothing would make me stop loving them. A partner is just that; a partner that one exchanges energies with. A marriage is a contract--you do this, I do that--blah blah blah. I have yet to meet the man whom I would love unconditionally (especially as a marriage partner) and expect nothing in return. I suppose it does exist in rare cases where one finds their other half. But I believe that is very very rare and could actually be counter-productive to the very real business of marriage, child-rearing, and society building (in fact, what's love got to do with it, ultimately? Romantic love expectations are relatively new to the human marriage institution).
With children, it's just there; hardwired in the moment you feel the quickening in your womb and know that another being has chosen to incarnate through you.
So, yes, I love my children more than any other being I have ever met aplanet. I believe this is as it should be. I shudder to think of meeting someone I loved more or equally.
