There was a lot more - since mid last summer the US and Iran have been talking. There was some progress on nuclear issues. However Iran refused to discuss their ballistic missile program or funding for the likes of Hezbollah. Just based on that alone it is no surprise that the US got fed up. However you have to pay a little more attention to see that even though it is public.
Sometimes you want someone to do something, but you don't have authority to order them around, and you are bad at persuasion and dealmaking, so you don't get what you want.
If you're not ok with walking away at that point, maybe put a better offer on the table?
