I don't think it's misleading. It's simply none of his business until I decide to tell him. I don't volunteer that I have kids. I don't lie and say "no" if the guy asks, either. But, since he won't meet my kids, it's not really pertinent to the relationship we're attempting to create.
I figure if he ever becomes Mr. Right potential, he'll already know I have kids by then.
Another reason I don't mention my kids is b/c I don't want a man thinking about that responsibility. They won't ever be his responsibility, as far as I'm concerned, so why even bring it up? A man and I recently "broke up" b/c he couldn't take it that I have 4 kids. All I wanted was sex every other weekend and phone conversation every now and then. He claimed that he only wanted that, too, but when push came to shove, he was in the future somewhere, marrying us off in his head. That's the only thing that could explain why my kids were an issue for him. He thought we had potential to make it long-term and wouldn't believe him when I told him otherwise.
It's really sad. I hope I never deal with that, again!
