Hi school started again and seeing my friend again. on the first day of school i saw him and he did talk to me but not very much. then later on i saw him ,and asked if i could sit with him at lunch and he says you can say hi too me. then later on last block we walked to the next class together and that went well ,then after school ended we walked to the bus together. the yesterday went he talked to me and stuff. then today went okay. in the morning i went to see him and he says hi quietly. he was with his other friend. i had the feeling he was trying to avoid me or mad at me. then when we were by ourselves i said your are my friend and then he said it to me too but quietly.then before we said goodbye i tired giving him a hug but he would not give me one. then later on at lunch i went over and i asked if he could sit with him and he yeah but quietly. then later i saw him and i walked to the bus with me. and then i asked if we could text and he says maybe. what is going on? am i seeing things that are not there ?
Btw we are both males

Tell him how it is. Don't beat around the bush. Tell him how you feel and ask him to clarify what's going on. I hope things work out for you
