It's rude to push expectations onto a new love interest.
Ben and Dana have been dating only a short while and Ben had told Dana he wants to get married eventually and Dana is hesitant.
Ben wants to comment on Dana's hesitancy to marry him.
Ben tells Dana that he's only talking about an eventual dream and that she need not feel pressured.
Ben tells Dana that he insists they get married very soon or their relationship is pointless.
Dana is relieved that Ben didn't mean he wants to marry her right away and is open to exploring the future with him.
Dana is quite turned off to be so pressured and ends up just breaking up with Ben right there.
