I've haven't had any serious relationships in highschool and its because I was pretty bp. Now I'm a senior(post rp) and I asked an attractive girl to my homecoming, she said yes and we hung out a couple of times. She said she wasn't ready for a relationship, but homecoming is in one week and I didn't realize it but I got one-itis for her pretty bad. I still plan on making a move but I'm thinking about her all the time and its getting bad because like I said she doesn't like me. I've been trying hard to get over her but she is one locker away from me and she walks with me to every class. Any advice stopping this particular one-itis?

Tl;Dr : See this girl all the time every day and I can't get over her, and she doesn't like me.
