Yeah. I'll nth the don't date women with kids thing- whether you want to or not, whether the kids have a father or not, you will get dragooned into playing daddy. Unless you're just dying to play daddy without the benefit of it even being your kid, just avoid it. It's 2009, birth control exists, there are girls out there who are smart enough to use it. Then again, if that's your thing, go for it. Don't worry, by the time she forces you to sell your bike and get a minivan, you won't remember your manhood enough to even be upset about it.
