Female cousin keeps sneaking glances at me.

For context I’m 22 male and my cousin is 11 female. I’ll often catch her looking at me and when she notices she’s been caught she’ll look away and pretend if never happened. If it was just once or twice I wouldn’t be bothered but she does this every couple of minutes. I’m not sure what she’s doing this for but one time I turned on my phones camera mode to count how many times she does this because I was curious and found that within an hour she had done it almost 60 times. I thought she’d stop with time but it’s been almost a year and she still does it. It’s to the point where I can tell who she is by how much she looks at me(she has a twin sister who looks the exact same). Her twin sister doesn’t seem to care at all about my presence so I’m very confused about the situation
