Hello Kisa_411,
Yes, I think that Jo could be right. With all the friends involved, he may feel a bit awkaward, and with all the misunderstandings & missed chances, he may wonder if you really like him.
You are both very young and I think that this kind of thing is very common at your age. I know that at this age it is difficult to speak direct to the boy ~ or girl ~ concerned, but it is for the best. It can help stop the misunderstandings.
When other people are exchanging messages for you, they can get mixed up.
Good luck!
