hello there, pls advise me on the following. my bf and i had an argument today and then a fight about the way i responded to something he said. reenactment: "damn! we always get caught in traffic lights", said he, while driving. and i said "oh what a drama" but with a smile. and so im supposed to have acted as a b.... for saying this, cause i was.. sarcastic. do you think i was rude to him? cause thats what he claims. he thinks i dont respect him and so on. on the other hand i claim, that it was just my sense of humour.,which he obviously doesnt like... pls do tell your opinion. thanks anyway.
