<human>: Can you condense the text into three sentences or less?

A little background: We've been together for over 8 years. She's in school full time while I'm working full time and paying most of the bills. She's very stressed at school and regularly having mini breakdowns. I've tried this past year to be supportive, and it has been a very difficult time for us.  
  
I've recently taken 2/3rds of my savings and paid off my car loan in full. About a week before that, I told my partner that I had enough saved and I wanted to do it. She told me not to do it and keep that money as an emergency fund.  I thought about it, did the math and realized I can keep us in the black and still pay it off. So I did. Now she's saying she can't trust me and I'm a liar and I should have talked to her about it.  
  
I'm feeling like I'm the adult here, and I've taken a huge positive step forward with my finances. Yes I should have talked to her again, but she's been literally lying on the floor freaking out from school stress, so not exactly in a reasonable state of mind. She's pissed off at me now, but I'm really not feeling sympathetic here. Actually I'm very disappointed that she's not happy, and makes me wonder if she really understands how debt works or if she trusts my judgement at all. Any feedback would be appreciated.
<bot>: Seems like my stressed out girlfriend doesn't trust my judgement and is now pissed that I paid off my car loan without her consent.
