If a guy purposely walks right in front of you and intentionally crosses your path even though he doesn't have to, what does that mean?

he walked out of the hallway and looked directly at me, where he knew I always walk while I "wasn't looking" and crossed purposely until I looked at him looking at me and said hi and walked past?
