Ehhhhh
That totally negates the persons right to not date someone with kids on any level.
this makes no sense. so they dont tlel you 6 months in after you decide to get serious then what? what if i had a rule i don't want to get serious with anyone that has a kid? then its my fault after 3 months that I break it off after she tells me? this is why they should mention it up front.
If you ask and they say “no” when they really have kids then yes that’s deceptive. But if you don’t ask and they don’t volunteer that information then I don’t see an issue.
