<human>: Can you give me the gist of the text in a nutshell?

It's starting to become a problem for my girlfriend that I can't get over arguments as fast as she does to the point that we are lovey dovey again. She needs hugs and affection and she is solid, I on the other hand can't turn it off as easily. Unfortunately it lasts the next day or so. After I explain to her that I need time to sort things out in my head and will calm down eventually but during it is understandably misconstrued that my silence and desire to keep to myself is aimed at her. She takes it to heart and has told me that A) It makes her feel like I'm "punishing" her while I'm still doing my thing and B) She takes it to heart that she can't do anything to make me feel better.

I really don't have any other way of soothing myself other than just keeping to myself and whatnot and I feel like I can't get that when I feel penalized for it because it upsets her. I have explained this to her but it doesn't seem to help. Does anyone here tend to hang on to emotions longer than normal and how do you deal with it?
<bot>: OP needs to know if staying upset for a day after an arguement is normal, and how to deal with it so that it's duration doesn't last so long.
