Does this guy like me?

Ok so I here everywere that if a guy likes you he"ll start walking slower to match your walking pace. So there's this guy in my class i kinda like and we were walking next to each other and he started walking slower but very slow almost barely slower than my pace. Then when we were walking towards the stairs he took the opposite stair way I took. so does he like me or was he just walking slow so I stopped talking to him and or walked a head of him? (also if it helps he's is a taller guy and im kinda shorter so it was noticable he was walking much slower than he would normaly.)

Does this guy like me?
