Search Results: look through my phone

For context, I'm 17F, and a Senior in high school. My bus gets there pretty early, about 5 minutes before the others do. A while back, I met a guy. Let's call him Ryan (17M). And once he arrives at school, he always comes and sits down next to me on the stairs. For the last two or so months, he's been getting really close to me. And I don't know if he's leading me on, or whether or not he likes me. So, I'm going to list 3-4 things, and hopefully, I can get some advice on that.

• 1: At an assembly a few weeks ago, he was just sitting there, looking into my eyes, not saying anything. And then one of my friends suggests he should sit and turn around so he could see, and he came up and sat next to me, and was leaning into me the entire assembly, showing me stuff on his phone.
• 2: A week + 1/2 ago, I carried a baggy red overcoat to school, and I had set it down on the stairs. We talked normally, and when we went to get up, he grabbed it, took off his hoodie, and put it on. I wore his, and he wore mine, for the day. He returned my overcoat back to me but didn't want to take his hoodie back, so I still have it.
• 3: About 2 days ago, he took my hand and was comparing his hand's size to mine. (mine is significantly smaller.) He turned my wrist over, and took the bracelet that I was wearing, off. Then again, he wore it for the whole day and then gave it back.
• 4: Yesterday, we were sitting, and he asked to play the game I was playing. I handed him my phone, and he was just playing. I was talking with someone, and was just letting him mindlessly play. He poked my side, told me it had turned off, and went to hand me the phone. Since I was busy I just told him the code. (a mistake I know.) My other friend left, and I looked over and he was just mindlessly scrolling through my phone, going through my photos and apps. (I had a few photos of him in my phone, which he smiled at.)

And here we are. Advice?
