<human>: Provide a brief overview of the text.

This is slightly embarrassing and I feel extremely shallow posing this as a concern. However...

I've been sleeping with my girlfriend (18/F) for a number of weeks and every time she gets sleepy, her left eye physically moves to the side of her head. When she opens her eyes, her eye moves back to its normal position.

I care very much for her and love spending time with her but it is really distracting me. It's just part of who she is and I totally get that. The problem is with me. I want to not notice it and not be bothered by it but it's so obvious when she's tired and is so distracting.

I'm not sure what kind of advice I'm expecting from this subreddit but I thought I'd ask. Thanks so much for your response(s).
