When DP and I argue (which happens more than I would like but I admit that we are probably both stubborn and argumentative!) she often swears at me- quite nasty swearing like 'fuck you' and she has used the c word on occasion. Now I swear quite a lot in general conversation with adults including dp, for example I will often use 'fucking' quite casually like 'i can't believe the fucking bus didn't turn up' etc, but I can't remember a time that I actually swore at someone, let alone dp. Is this normal in arguments? It upsets me and makes me feel horrible but maybe it is just a way of expressing anger. What do you all think?
