Why does he behave this way and his friends?

Like i be working and he works in a different area of the building which is in one building though and he often comes to me and backs into my space and i walked back ๐Ÿ˜‚ and he keeps walking forward and says โ€œ why are u walking backโ€ lol I don't know he's comin close thats why duh

Then the next day he sees me while walkin around instead of working ๐Ÿ˜† he takes my scanner off me and holds it up for me to get lol

His mate says to him im his girlfriend which a friend of mine told me who was there (I wasn't)

Then he comes to me and says oh my friend likes you (As in the one who playfully annoys me) ๐Ÿ˜‚ it is annoying sometimes

Then today again he came to me and asked to smoke outside and every time we talk he bloody pats my arm ๐Ÿ™„ which i feel insecure about ๐Ÿ˜‚
