<human>: Okay a little back story. We met in college in Alaska. Were friends for half a year before we started dating. Then it was a great year and a half. It was amazing. I enjoyed my time with her and I even thought about marrying her. Then she had to attend college in Ohio cause the course she wanted wasn't offered here. 

We were sure we could make the LDR work. I was hopeful. I'd send her packages of some silly stuff. And we'd talk on skype almost every night. Text messages never stop coming. Then the calls gradually became less and less frequent until it came into a complete halt. Then after half a year another friend of mine confirmed to me that she was cheating on me. I confronted her about it and we broke up.

 Last summer she came back to Alaska and begged me to get back together. 

I really really liked her. I really do. Breaking up with her was the most painful thing I've ever had to do. So I happily agreed to get back together. 

We had a great summer then she went back to Ohio. At first we were back to talking constantly, skyping every night, texting, everything was great. Then again, it became less and less frequent. And just this morning I saw some guy posting on her facebook calling her sweetheart. I figured, it could just be a friend being silly. No need to over react. Right? 

So I asked her about it casually. Then she got angry at me and accused me of stalking her... Then she asked for "space"

And I know this is a huge flag. 

So reddit, I really really like this girl. I'm going to confront her again tonight. It might lead to another break up. Can anyone give me a good reason not to? I really feel like I should. But I really love her. I'm extremely indecisive so I'm asking you guys.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Girlfriend history of cheating, might be cheating again. But I really like her. I'm an indecisive fuck.
