<human>: Can you condense the text into a few key points?

**Sorry about grammar** 
So I have been with my girlfriend for about a year and 4 months
I moved with her halfway through our relationship back to the city she goes to school in for a few months until she finished. She cheated on me with her ex boyfriend out there and crushed me. 
I had no friends out there to talk too, ended up staying with her after we talked it out.
Ever since I have been suspicous of whats going on, we fight from time to time. 
She isnt the type of person to open up, she bottles everything in and its impossible for me to get her to open up.
Now im worried she has been cheating on me again, I love this girl so much and cant stand the thought about being without her but I am so distraught thinking about it I stupidly think of just giving up on life.
I am at a point where I dont have friends to talk to about this and I need someone to speak too so that brings me here.
Whenever I try talking to her she gets really offended and wont discuss anything just shuts me out.
Sorry if this all sounds stupid. Did not know where else to go
<bot>: Girlfriend pushes me away time and time again but wont say she doesnt want to be with me, need help with getting over her if possible
