<human>: Can you provide a brief overview of the text?

I'm male 21, she is female 18.

I have no friends to talk to about this so I just need the best outside opinion from a stranger, please.

My GF and I have been together for a year and 8 months now. Obviously I love her, blah blah you know the rest.

Beginning about, 2 months ago, we started having communication issues and yesterday it kinda came to a very dumb climax, I'll make it as quick as possible.

We were leaving target and she was driving, she was backing out and she could not have gone left due to traffic, she had to go right. After telling her to go right, she kept trying to go left about 3 times before i said "What are you doing?" in kind of an aggravated tone. Well she sped into her parking spot previously in, threw her shifter into park and said "I'm about to fucking go off on you", "You just drive".

So I got out and changed seats and drove out of parking lot to go to dinner. The entire car ride she literally looked out the window the whole time without saying a word. When we got to dinner, i turned car off and got out the car only to find out she had walked way ahead of me (you know, to be rude) about 5 car lengths. I ran to her, grabbed her and said look, "I'm sorry for having a bad tone with you, but lets just stop this, its such a stupid reason to cause a fight." 

She pretty much blew this off and continued to be mad at me.
When i tried to talk to her any, she made comments like "mmhm, idk, whatever".

Later that night i tried talking again and she was very rude claiming I didn't do anything to remedy the situation, I'm selfish, and bossy.

She pretty much just broke up with me, but not 100%, can anyone just help me and say if I'm really wrong here in this, I know it's not a whole lot of info, but im having trouble focusing at all honestly.

If you have any questions, I'll try to clarify.

Thank you, really, for anything you have to say. :(
