Is he flirting with me or wants to be more than friends?

ok, there is this guy that I've known for 8 years. he's in 7th grade and I'm in 6th. I have a boyfriend and he knows that. well one day I was changing in my room cuz I had just taken a shower. without knocking he just comes in my room and I had my towel off! he said sorry and walked out. then the other day him and his family came over to eat. me and his little brothers and my friend were playing soccer. I got really hot and told them I was going to change into basketball shorts and get out of the sweatpants I was wearing. the door to get in my house from the backyard )where we were playing) is on the other side of my house along with the kitchen. well while I was changing he barges in again and says he was going to the kitchen! then we played some more soccer and I had the ball. so he tackles me (hands around me and everything) so I said "HEY! its not tackle football!" and hit him in the stomache with my elbow and he wouldnt stop flirting with me. does he want to be more than friends??
