Why did he say to my friend I’m his girlfriend when I’m not?

She likes him and always around him but he’s around me sometimes with his friends he comes up to me at work and just messes about and then helps me 😂.

so my friend told me he said infront of his friends “ (my name) is my gf” that’s what she told me. I did notice he’s always around me and stare smiling that one was werid like he wouldn’t stop stare smiling for good 4 seconds 😂 awks

he even worked in my area just to be around me because usually he’s on the other side but since he’s been around me a lot he has moved to my area and always swapping lanes with his friend to be next to mine.
