You know I was just thinking, your wife must be nuts to want to raise 4 kids on her own. Most single mothers have to work and I struggle with my 2 and holding down a full time job. I'm not saying you won't be involved in their lives but honestly..if y'all get divorced does she really expect you to come "home" every night and help her? I just do NOT understand why any woman would chose to be a single mother (I'm not talking about women who are mentally or physically abused).
