TIFU by not hiding my books

So I (17m) and my best friend (16m) are both seniors in HS, he'll be turning 17 in December. We've been friends together since 3rd grade and were always inseparable. Our teachers should say we could be siblings if we tried hard enough, this was in part because our mothers both worked for the same companies with his mother being my mom's superior. Anyway, we stayed with each other and usually found other friends but stayed closest up until around junior year. That year we both decided to challenge ourselves and take 4 AP classes to boost our weighted GPAs since they were only 3.9, and we both wanted to get into a good university with him aiming for UCLA, Rice, and Cambridge and myself looking for Umich, U-Washington, and John Hopkins.

But anyway, our moms noticed that last year and this year we started drifting apart (due to being so busy) and tired of getting us to talk and spend more time with each other because we might not end up going to the same school or even seeing each other much after we go off. Now I'll admit, the workload this year and last was actually kind of a relief because I'd fallen in love with him some time back in 7th grade and just never brought myself to confess. Anyway, one thing leads to another and they decide that we should spend the Thanksgiving break with each other since it's a 5-day weekend thing. We both agree since it's been a while since either of us could find a break and so he comes over with his usual Xbox and manga.

We spend some time having fun with it and then he asks me after our 4th round of DBD if I still draw, and I tell him that I do every now and then. Now here's the thing, I used to take art lessons as a child so from a young age drawing in an anime art style was harder for me than just something like semi-realism. So that is to say, determining something isn't as labor intensive as if it were something like a cartoonish art piece. I tell him that on my bookshelf I have a bunch of novels, sketchbooks, and manga if he wants to read some. I'm shutting down the Xbox now and heading over to the kitchen to get snacks and I come back and see he's looking at a green sketchbook and has a manga on the floor.

I recognize it as the sketchbook that I use to make art of him, some in glorified pieces and others in more sexual ways and the manga he has on the floor is a copy of a yaoi manga I have. Then it hit me that I forgot to hide those. I usually stuff that kind of stuff in the closet when people come over and take it out when they leave for easy access since I'll sometimes use them or draw in them late at night. I then grabbed the book and all of the other books, manga, novels, etc. that have anything remotely gay or things to do with him threw them in my closet and proceeded to try to laugh it off and tell him that I sometimes look at those things from time to time because I might be bi.

He just agreed but seemed unsure and we went back to playing video games and watching JJK. Afterward, we ended up talking about him and how his cross-country is and such things before he asked me when I wasn't expecting if the sketches I did were of him and if I wanted to do those kinds of things with him. I rejected it immediately and told him I could never see us as a couple and that the thought of us together was honestly horrible. He seemed to just accept it and didn't bring it up again anytime later. After that when we were asleep I think I heard him maybe crying but I'm not sure and I'm also unsure about how to go about for the rest of this weekend. I want to believe that he maybe has a crush on me, but at the same time, he might just feel sad that I hid my sexuality from him for so long despite us being best friends. Does he like me or am I overthinking it, and what should I do? I don't enjoy seeing him upset or down.

TL;DR: My friend came over and I forgot to hide my gay books and he may have discovered I have a crush on him but he might also have a crush on me.
