<human>: Can you condense the text into three sentences or less?

I am a 15 year old female, and have a boyfriend of almost year, who is 16. I honestly love him dearly and honestly don't want to leave him. He treats me every well.
I have a friend, male 17, who I've recently become close to and noticed myself crushing on him. He also treats me very well and is funny and cute. I don't really flirt with him and I would never do anything with him, but I do get very giddy when we talk/hangout (only in group situations do we hangout). I don't plan, nor do I want, to become anything more than friends, but I do want to keep him as a best friend. 
The issue I'm having is that I feel guilty for crushing on someone other than my boyfriend, I feel like its wrong or unfair. 
I don't know what to do, because I don't want to lose my relationship with either, but I don't want to feel guilty about liking him. My boyfriend and him get on okay, and he doesn't mind me talking to him. I just don't like feeling guilty for something.
<bot>: finding myself having a small crush on a friend when I've been in a relationship for a year. Don't like feeling guilty, but also don't want to lose the relationship of either.
