He call me his buddy does it mean that he juz wanna be friend?

We started talking recently, its weird bec0z we have each other's number but we dun call each other until recently, 0nly bec0z he asked my c0worker abt me when he dun see me at work. When he saw me at work I asked him y was he looking for me but he didnt ans me after he left he text me talking abt e reason he asked abt me that day was bc0z he wanna see if i wanna do lunch with him. I kinda think he is interested in me until he start calling me his buddy when he call or when i call him. So does it mean that he is really not interested in me ? He juz wanna be friends?
