<human>: Give me the gist of the text in a nutshell

I have been out of town for a week to interview for a new position. I had been working towards this goal for the last few months and due to a careless and stupid mistake on my part I failed. I am not happy with myself about it and have been kicking myself over since it happened two days ago. Most people have told me that it's not that bad and I shouldn't be so hard on my self but I am a bit of perfectionist and I am having a hard time with this because it's still fresh. I am sure I will be fine and move on in a day or so but today I feel like an idiot and subdued today. I have just been quiet and introflective. 

Fiancee knows that I am upset and kicking myself, we texted and she seemed supportive and reassuring through text. I got back to our home state today and expected her to have a similar attitude to our conversation. What I got was not that. I got the cold shoulder instead. I small hug and forced kiss. After that she basically ignored me and went out of her way to not be around me.  

I understand that a bad mood is contagious but I wouldn't even say I'm in a bad mood, just bummed out. 

I tried to talk with her to see if she was alright and she acted like my behaviour was some sort of personal attack on her. How me coming back from this trip early had thrown off her social calendar. 

I thought coming home would be a safe haven from the questions of my colleagues and looked to her as my rock. Instead I'm feeling pretty stunned at the total lack of compassion from her.  I feel as though I have may have misjudged my perception of her and the strength of our relationship. It seriously makes me question how she will react if something else goes sideways in life, something major, will I be able to count on her or should I just be my own support system and let it slide.
<bot>: I screwed up and I'm pretty bummed out. SO was supportive over text and completely uncaring in person at took it as a personal affront to her. Not feeling the love when I could really use it.
