<human>: Summarize the given text in a few sentences.

I was working as a junior designer at a bakery chain last christmas. Since it was a crazy season, I had to stay long hours and spend a lot of time at the office with my boss. He would treat me nice and compliment me on my looks but I never liked him at all(he has a very funky smell, wears dorky clothes and only theme of conversation is football and Rambo, not my type). He finally texted me that he liked me and that he would like to date me to which I didn't reply and things got awkward at the office. I could feel him staring at me and he would ask me to do chores that didn't correspond to me as a way to have moments alone with me. It became too uncomfortable for me so I quit. Not too late after that he sent me a FB request which I turned down. Then he would call me and I never answered. Last thing he did was sending a message on FB and I  had to block him. I thought it was over but he texted me again last night. I don't understand why he would keep trying? most guys give up after first attempt. I've never been through this situation before. 

I want to know how can I let him know clearly that I'm not interested on him at all in any way and that I want him to leave me alone. I thought about texting "I don't like you, I never will. Please leave me alone" but my friends say it's too brutal. What should I say instead?
<bot>: Former boss likes me, I don't, keeps trying to contact me even if I rejected previous attempts/How do I tell him I don't like him without being too brutal?
