The Ultimatum --WTF

So obviously these people are wild, they are on a show about giving their person an ultimatum and my thing is... didn't they have these conversation when they met? Like "hey do you want kids", "hey do you want marriage?" AM I INSANE.

Also, 80% of these people (if not more), really do not love the other person, they just don't want to be alone.

PS. Nick and Vanessa are 2022 version of Tyra Banks.
