Things are said sometimes in the heat of the moment, without thinking of how it will affect the other person. With that being said, I am taken aback by him dropping the "f" bomb on you as well as telling you to shut up. Granted, I do not know you or your situation. But from one person to another, you should never be told that under any circumstances by anyone.

It could be that your boyfriend has many problems that are causing him great stress and he is taking it out on you. Again, that is something no one should have to be dealing with from anyone. And I hate to say it but the only one that can tell you how he feels is him. Have you contacted him since the argument?
