Navigating Feelings: What's Allowed When You Admire Someone in Islam?

There's this amazing library in my town that's perfect for studying. I started going there more often around October 2025, sometimes two or three times a week. During winter break, I was there even more because I really needed to focus on my studies. There's this brother who's there almost every day-whenever I go, he's there. I actually recognized him because we once took the same bus near the library back in March 2024. The reason I remember him is a bit strange: I had this random thought about pulling his hair (I didn't do it, obviously!). When I saw him again in 2025, it all came back, but I didn't think much of it at first. Slowly, though, I found myself wondering, 'When will he arrive today?' I started caring about his presence, and my mind even picked up on the time he usually comes. I began looking forward to prayer times not just for salah, but also to see him go down to pray (the prayer room is on the first floor, and he usually sits on the second). I normally prefer the second floor because the first floor can be noisy, but in winter, the second floor gets too warm because of the AC, so I had to move downstairs. Anyway, I realized I like him. Being honest with myself, I admitted, 'Okay, I have feelings for this man. What do I do? I shouldn't act on it.' From what I've seen, he's very religious-he prays on time, often leads the prayer at the library, and has a beautiful voice when reciting Quran. He always lowers his gaze and avoids talking to women, and he's respected and well-liked by the staff. I told myself I don't want to be the reason he does something wrong. Even if it's just showing interest or staring, he might notice, and it could make it harder for him to maintain proper interactions. So, I decided to keep my distance and admire him from afar without him knowing. Here's how I tried to avoid acting on my feelings: 1. **Where to sit:** Even though summer is here and the second floor is comfortable again, I stayed on the first floor despite the noise and some uncomfortable encounters. 2. **Prayer times:** I wasn't always punctual with my prayers before, but seeing him pray on time inspired me to do the same. I'd wait for him to go to the prayer room without seeing me, then I'd go in to pray and leave after he did to avoid meeting. 3. **Breaks outside:** When he steps out for fresh air, I make sure not to go outside at the same time. 4. **Bus rides:** We used to take the same bus home, and I couldn't afford a taxi every time. So, I'd get on the bus first and act busy when he boarded to avoid making eye contact. But things got tricky: 1. The first floor became too distracting with unwanted attention, so I moved back to the second floor, choosing a seat far from where he sits. 2. Timing prayers perfectly became exhausting, and a few times we ended up leaving the prayer room at the same time. 3. I can avoid going out when he does, but he doesn't do the same when I'm outside, so we've bumped into each other occasionally. 4. The bus situation worked out because now I leave earlier than he does. Lately, I've noticed him glancing at me a few times-not staring, just briefly, and our eyes have met when they didn't before. It feels like he recognizes me now. Part of me is happy because, well, he's my crush and I wonder what he thinks. But I'm also worried: am I doing something wrong unintentionally? Even without trying, could I be sending signals? I genuinely don't mean to. What should I do?
