<human>: Can you give me a shortened version of the text?

So, met this girl eight months ago, had a great time with her, love her to death.  

And this past month, she's been shying away with what she's texting and chatting, both who and what they're saying, something she never used to do as we were both very open with eachother.  

Every time I need to think, I go outside at around 10pm and sit by the river near were we live.  
Usually that's that, I go back and we hang out and go to bed.  

But today, after coming home.  
I find this note on the drawer in our hallway:  

"I'm sorry for this. I really love you, but I love him more.  
I can't really say what it is, but he's offered to take me and the cats to his place.  
I always loved you -my name-.  
I'm sorry"  

She left her SIM-card snapped in half, all her social media accounts are deleted.  
I don't know what to do, please help.
