<human>: Long story short. Met a girl in English class last year. She was really sweet and we joked around a ton and became really good friends. I always joked that she was my "adopted freshman". I honestly thought of her like a little sibling. We would just hang out and joke around. 

Well she recently became single and is having a really though time. I wanted to be there for her so I'd send small texts like "How are you feeling?" "Is there anything I can help you with." After a few days of this I asked if  she wanted to watch a movie and vent. She agreed and we ended up spooning on her bed. 

I like to cuddle, even if its with platonic friends. Here's the issue, my little soldier stood to attention and now I'm uncomfortable. My brain was horrified, shes like a sister to me, but my body was super into it. I shifted before she noticed and let it cool down but now I don't know what to do. My heads telling me its weird and that's not the kind of relationship we have but spooning with her felt really right.

Can you give me the gist of the text in a nutshell?
<bot>: Spooning with a long time platonic friend, ended up getting a semi. Now I'm questioning the platonic part of our friendship.
