Questionable thinking

I absolutely adore kids. They are so adorable, so sweet, and absolutely sincere. I can't wait until I get to raise my own kids someday. Everyone tells me I'll be a great mother, but I can't help but doubt my own ability. I have so much love to give and I would love to give my whole heart to someone and love them unconditionally.

But what if I can't do it? What if I turn out to be a terrible mother? What if I'm just not meant to have kids?

This is the thought process that comes up when I start liking a guy who already has a daughter. She's already the love of his life and I think it's wonderful how devoted he is to her. I don't want to step on any toes and be the "step mother" but....what if? That's the problem with getting older. The guys I date might actually have kids already. I don't mind being a step mother, but what if I'm just not good at it? It would break my heart if the kids didn't love me in return.
