The hardest thing I imagined about being a stepfather is having to face that sentence sooner or later, if you were in the situation how would you respond to something like that?
I don't know I think I'd try to show them that even though I'm not their biological father I still care about their well being and only want what is best for them.
I don't know. I think I would explain them that though they didn't consider me as their father, I would still consider them my own kids. Not all step children are that rude to their step parents though.
