I was too scared

He went to my high school and we were in the same clubs together. He'd often help me with alot of stuff so I owe him alot. After the thr first year I met him, I started crushing on him. His friend snapchatted me and told me he (my crush) liked me. I didn't believe him and plus there wasnt anything I could do at the time since he was in a reletionship. (His friend told me that my crush hated his then gf) Then he graduated and he hasn't spoken to me since. I thought we were good friends and I watched some of the anime he liked just so he could notice me. He didn't. Now he has a new gf. I like to think there wasn't much that I could do...
