My stalker at work won’t stop talking to me.

I can be mute for 20 minutes straight and he’ll still have conversations as if I’m listening

he called me rude cause I won’t get off my phone and talk to him. sir! this is my lunch time I’m gonna enjoy the 30 mins I have to be on my phone

so he kept bugging me today asking if I wanted to be left alone. I told him yes. he didn’t listen. he kept insisting to have a conversation with me, even told me he had some type of feelings towards me and asked if I was okay with that. I said I didn’t care, he then asked me

also offered me a piece a gum but kept pulling it away, every time he would act like he was gonna give it to me he tried touching my hand. I pulled away and didn’t take it
