Be honest - can you treat your partner/spouse's kid(s) as if your own?

The society now has over half the marriage end up divorced and that means more than 50% of the kids live with step parents. Are you a step mom or dad? Can you really treat step kid(s) as if your own? Do you have the unconditional love toward them? Do you want to give the best of you to them? Do you want to do better yourself just for them? The reason that I am asking these questions is that I am a single mom at the dating scene. I want to set the right expectation to the potential partner. Thank you.
