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

Throwaway because my friends know my username.
I have been dating my girlfriend for a year now and I've always tried having an exciting relationship. Anna and I have never had any major arguments and we have always had fun with each other.

 However, two months ago she started acting a little more different. She did not tried to find me as often as she did before and she preferred going out with her best friend and not me, even though they spend half their time together.

Yesterday a lot of things happened. I came back from a trip and I had asked her not to make any plans for Sunday, so that we could hang out. But of course, she told me she was meeting up with her schoolmates, so I met up with some friends and after coming back home, I called her.

She told me that I have always been supportive of her and I was the only man she had feelings for, but she felt as if there was a gap between us and that there was no progress at the time. After that we decided to take a break from each other so that we could clear our heads and decide what would be best for us. 
I am really lost and don't know what to do, please help.
