I think I like my friend, but do I like him just because we spend so much time together?

I started getting closer with this guy in my friend group in the past month or so. It’s gotten to the point that we hang out everyday, for the majority of the day. We definitely prioritize time with each-other and have gotten very close. I do find him attractive, even though he is definitely not the type I would typically go for. But over time, I’ve really come to admire him, appreciate him, and thoroughly enjoy spending time with him. I would say I have feelings for him, but I’m afraid that its just infatuation or confusing feelings since we spend so much time together. I most afraid to end up hurting him in the long run.
