need guy advice: did i scare him away?

[Katelin]

so i'm at college and i met this guy and he added me on facebook then asked for my number the next day and i thought that was kind of bold but i liked that he took it upon himself to get my number. so we txted almost everyday and he would txt me good morning and my friends and i had some suspicions that he liked me so when i asked him he said im not sure yet bc im not ready for a relationship. and he asked me back and i told him i didnt know yet either. but i do like him now and after we hungout one time with a group of people he started acting weird. i told him that i wanted to hangout again but 1 on 1 and he thought i was being sexual but i wasnt. so i asked him two times to hangout and he wouldnt never respond and i called him out on it and said "you dont want to" then at a football game i walked up to him when he was with his friends and he didnt really talk to me at all and pretty much ignored me so i ignored him when i saw him days after that until he said hey to me and that he would try to meet up with me later. he never did and he doesnt txt me ever really like he used to, i dont know wat i said or did but i feel like maybe i came on too strong by saying we should hangout and stuff. any advice?
