Unpopular, but I couldn't consider dating a single mother

I know, I'm evil, even the government says I'm evil for not footing the bill, but there is logic in my reasoning. I want a kid of my own some day, which is fine, but once I do, I would almost certainly spend most of my time and attention on my child rather than hers, which wouldn't be fair to her child. So I guess being the bad guy in this choice ain't too bad if I save a kid from having a neglectful stepfather.

Why am I thinking about this? Well I like to cook, which means I know what to get at grocery stores, and I'm at that age where a grocery store is prime dating real estate.
