I feel like my 10 year old hates me

I feel like my 10 year old hates me all of a sudden. Like his attitude completely changed as soon as he turned 10. He went from a sweet, funny, loving guy that always wanted hugs and constantly told me how much he loved me to this moody, grouchy, pouty kid who ignores me when I talk to him, only wants to play video games online with his friends, doesn’t like to spend time with me and always seems like he hates me.

I don’t get it. What did I do wrong and where is my sweet little boy who would always make me choose the lucky stuffy of the night out of his stuffy collection for him to cuddle with that night. I don’t like this phase in his life one single bit.
