When a guy you have a crush on plays footsie with you all the time does that mean he likes you? i need to know

See he is my brothers friend and i think he is really cute and he comes over to stay on the weekend with us well we went to see a movie this weekend and during the movie he would reach over and start rubbing his foot aginest mine and he would touch his elbow aginest mine and i would just love to know if he likes me.
