In the same way, I'd expect my partner to have disclaimers of their own about how they lead their romantic lives and their family lives. I'm not ready for the responsibilities that come with the latter and I think it's better for everyone involved that I disclose that going in. My role, as of right now, would be that of a romantic partner, not a step-mom. For me, it would come down to how we define our relationship. Of course, they'd have to be OK with my views on parenthood, too, but I think it could work. Truthfully, if I ever found myself genuinely interested in someone who happened to be a parent, I would be willing to give it a shot. And even if I am, I don't have any real interest in being one, which is fine by me.
I just don't know if I'm cut out to be a mom. It's not like I'm Meredith in The Parent Trap who was eager to ship her fiancé's twin girls off to boarding school.
As a woman who doesn't want kids of her own, I've always been a little apprehensive about dating someone who has a child.
