<human>: Can you give me the gist of the text in a nutshell?

Hello everyone, I was worried that my girlfriend of 9 months was cheating on me a few days ago. She was always on her phone texting away and whenever we would text, she takes long to respond now. After too many times of this happening I asked her why she is taking so longer than usual to reply, and she just said shes busy alot of the times. 

When I last went to her house which was yesterday, she left her phone behind as she went to go get changed. Curiosity was killing me and I snooped through her phone, I know this is not good in many relationships but what choice do I have? 

What I found was what I was looking for from the beginning. She was talking to this other guy through the app Kik, and constantly the guy hit on her calling her beautiful and cute. Now this is what really did it for me. She was sending pictures of herself to the guy as he kept giving more and more compliments to her. Whenever I ask for a picture, she hesitates and always complains that she does not like taking pictures. Now what's the big deal now? Why take picture for some stranger? The pictures were also quite revelaing to her cleavage and the guy complimented on that too. All she replied was with agreeing with him and was flattered. 

Now, the guy basically asks her if she would date him. And she said totally, without a thought about me. I was texting her at the same time she said this too, and they are now in a long distance relationship behind my back. I dont know how to confront her over this and it really breaks my heart to find this out. I never expected her to cheat on me, what should I do? Please help.
