I have a crush on a guy, and I told one of my friends I did. That friend said she also thinks the guy I like ,also likes me. He shows some signs, even if its in a platonic way, like making eye contact when we are talking to each other, looking at me when I wasn’t looking at him but talking to someone else in the group, coming up to talk to me, and I make him laugh and i’m a bit nervous when we are alone together, I think he is also nervous too. Maybe he is uncomfortable with me? He is a little shy. We are both a little shy, I would say we are the same mix of extrovert and introvert. and I feel we both put energy into keeping conversations flowing. I know I must really like him because I feel jealous when he is with other girls. I also feel my friend also likes him, as she was flirting with him, and when he is with her, he looks more comfortable and i’m hurt as she’s the only one in the friend group that knows I have a crush on him. And I feel like he might like her better now. He said to me that she was really nice once.What should I do to just forget about him and focus in my studies.
