I would like some opinions about this certain scenario.
A couple, (in the sense they are dating each other exclusively) get into a big argument. They have only been dating 3-4 months.
The argument: The man is driving and they are talking to one another on the phone. He tells her there is a cop behind him. Then he tells her the cop is pulling him over and he has to let her go. She says , "Call me and let me know what happened" he says "ok". She waits, and waits, and waits some more. no phone call. An hour goes by. Thinking the worse and already mentally arranging bail money, she decides to call a mutual friend of theirs.
When the friend answers, she starts explaining what had happened, the friend tells her the boyfriend is there at his house, she hears loud music in the background, and her friend tells her there are a few people at the house. She is livid, she hangs up. Then she calls boyfriend on his cell phone. When he answers she calls him a thoughtless jerk, and a few other things. and hangs up. She calls back and is crying and tells him she no longer wants to have any sort of relationship with him, none, and hangs up again. But this time she hears him say, "I don't need this". She calls back again, and tells him she is sorry for caring too much, and worrying bout him. She is being sarcastic. All she wanted was a phone call telling her the cops did not take him to jail and he is alright. She thinks he is an uncaring selfish jerk.
What do you think? Did she overreact? or??
