“Behave hysterically” = Giving a “friend” an ultimatum to barge into her marriage and then dating her husband
I really think you need to revisit the idea of friends. I hope you are making this up to get Medium readers and doing a good job of it. If this is your ACTUAL life, you are a glutton for punishment and Nina is the reason I would be drinking nonstop. My guess is she is a factor for you too. No one needs friends this bad ever.
