<human>: Relationship lasted a year and six months. There's way too much info to list honestly, and our break up was no more than 2 weeks ago and it still tears me apart. 

My issue is confusion, denial, and loss. I should hate her and not want to be with C, she emotionally cheated on me. That's the reason she broke up with me, because she didn't feel like a good person. 

Yet here I am, puzzled, wondering whether I should go back to her house to pick up my guitar or have her sister meet me somewhere with it instead. I've only talked to C once since she broke up with me, and last night she texted me to remind me of my guitar. Truthfully, I want to go get the guitar just to see her and hug her one last time, but I'm afraid it'll be like previous break ups, where I break down about how much I love her and how much i will miss her. 

I think I'm mostly afraid of rejection. What if she just leaves the guitar out in front of the house for me to grab rather than handing it to me face to face?

I've read so many posts here similar to mine, but I never really realized just how hard headed a human brain can be. I'm way too attached. I want to be with her, i love her, and I get along with C the best. I can only be myself around her and i don't wanna lose her. 

I don't really know what I'm asking. I'm hurt. I have so much more I need to let out about the relationship.

Can you provide a brief rundown of the text in within 3 sentences?
