If you upset your girlfriend do you feel GUILTY or just blame her & get angry at her for confronting u bout it?

Right , you go round to cheer your girlfriend up as she's having a bad downer kind of day due to stress etc but you c*ck up and make a mistake which hurts & upsets her & when she tells you she is UPSET about it do you go into offensive mode and not fess up and say SHE is in the wrong and going loopy over her problems which you were trying to cheer her up with or do you AT ANY POINT feel guilty that you went round to cheer her up & make her feel better but you ended up making her feel WAY WORSE

I mean if you were really concerned about her wouldn't you just admit your mistake or not even admit it BUT AT LEAST APOLOGISE FOR UPSETTING HER

( I didn't have a go at him or anything , just told him I was upset about what he had done but he just went angry and bollistic and denied it and said I was crazy when I am actually not ..... spose all I wanted was a simple apology! ) :-( :-( :-(
