Joe knows a lot of what he's talking about.  Since we're using anecdotes, let me tell you about my single-parent niece who became a mom:  long story short, she's now a drug addict and her son is dead, notwithstanding the estranged father's best efforts.  But she probably looked at someone like you and thought, "Hey, I can do that."

If my niece had married the father, then had the child, chances are she would not be a drug addict, and their child would still be alive.
