I could really use some advice. My younger brother is 16 years old, and recently he's been acting and doing things which are quite upsetting to me. It all started when I was in bed one morning, and I wasn't completely awake, so I was pretty groggy. I felt something moving up my leg towards my butt,(my skirt had somehow gotten flipped up while I was sleeping), and rolled over to see my brother standing over me. He hastily jumped back and pretended to be doing something else. I just brushed it off thinking I had imagined it, but a few minutes later I rolled over again, and my brother was still in my room, only he had moved closer to my bed again. I told him to go out, and puzzled over the event throughout the day, but eventually I just brushed it off again. A few days later, he said he wanted to watch a movie with me in my room, so I agreed thinking nothing of it. Well, I fell asleep during the movie, and once again, I woke up to the feeling of something moving up my thigh, underneath my shorts. I jerked awake and angrily asked my brother what he was doing, but he acted like he barely awake, and rolled over. I went back to sleep, but it happened again during the night. My heart started to pound like crazy, and I was freaking out. I didn't really sleep the rest of the night. I haven't slept in the same bed with him since. The last thing he did which really, really upset me was a few days ago. I had on a knee length sundress and I went to the kitchen to grab a drink.For some reason, he was standing really close to me, and would move whenever I moved. I turned to face the counter, and then something told me to turn back around. My brother was crouched behind me, holding his phone facing upwards, directly underneath my dress. I think he was attempting to take a picture of my crotch. Once I turned around, he jerked back up and I angrily demanded to know what he was doing, and he just looked at me in a really weird, sheepish way. Since the incident, I've been avoiding him, and whenever I do interact with him, I get really pissed off and aggravated. The whole situation just makes very angry, but I wish I wasn't, because we are very close, and I really don't want this to ruin our relationship. I haven't confronted him about it, and I have no idea what to do.
