@boomerang,
I kind of agree with both here - I think I might feel an emptiness if I didn't have kids, but I am not sure - no one to know as I am not in that situation, but did I need them to feel complete - I don't think so. I think they added to me. I think I was complete before.
I loved my life when I was single before I met my husband. I got married older in a sense -- I was in mid-30s. I thought I would like to me married and have kids, but I loved being single and jet setting around too. So I wasn't in a hurry and didn't want to just get married to in using your words complete me. I was happy.
But then I met someone and we wanted to be dedicated and married to each other. We both love kids and wanted them so we planned and had them. It wasn't to complete us - it was maybe to add to our love and lives. Am I more complete now or happier --- no - sometimes being a wife and mom really stinks and is hard. More often it is the best thing in the world. I think it is just different.
I wouldn't change anything though - once you have kids as crazy and angry they can make you -- the ups are so much more.
Besides when they get to be teens it is quite fun to do things that embarass the h*ll out of them in front of their friends.
