My husband was away from home for one night. Just one night and I missed him greatly. I missed him because he wasn't here and I enjoy his company. I also missed him due to the fact that he wasn't here to help out with the kids.
I admire all the single parents and pseudo- single parents (those that have traveling for business husbands). I really don't know how you do it day after day. My kids are not necessarily difficult by any means but I do like having the helping hands around. Life is so much easier when there are two of us to share in the responsibilities.
