Recently I have been seeing this specific guy around my college, whenever I'm with my friends he always seems to be passing by me or just in the same building as me. I go to quite a big college so I might just be overthinking it, but I have seen him around so many times that I'm starting to think it isn't a coincidence I keep seeing him. For example, one of my classes finished early and I decided to walk around my college and I walked past the library completely oblivious to the fact he was sat at one of the computers facing the windows that overlook the corridors and I made eye contact with him and I immediately broke eye contact because every time we make eye contact I get a weird feeling inside of me. I kept walking around until my friend texted me asking to meet her and I walked back past the library and he was still sat there and we made eye contact AGAIN, but this time we kept eye contact for a few seconds till we both looked away. And another time I was with my friend outside of the college cafeteria and I was eating some food before my lesson started and he walked out of the cafeteria by himself holding a water bottle and we made eye contact and I broke eye contact because I got nervous. I guess what I'm trying to say is I keep seeing him in my college all the time and he is mostly with this other guy who I'm assuming is his best friend and every time I do see him we always see to make eye contact, I haven't spoken to him before but we always see each other at the same place and every time I walk past him, him and his friend stop talking and go silent whenever I pass by them. Is this normal? Am I overthinking it? Is it a coincidence we keep seeing each other? What is going on?
