This married man send me love msg how i should stop him?

he got my phone no from my work places i didn't reply him but in the 2 last weeks he started to send me some love msgs , i told him i am married and don't like to talk with any one , i reacted in the way that i didn't know him because i didn't want to make him more cheeky , he told me i know you well i have came to your work places for some contracts in the past and i feel you are a lovely girl i don't want to act saucily toward you i respect you but sorry i cant stop myself to love you he didn't introduce himself but told me let time tell you i told him whoever you are or what ever you think isn't important for me never msg me after this , but still he send me at least one msg in a day though i dont reply his msgs , but recently i heard from my friend that he is coming to my work places and check me out from afar . i don't care him but i don't want any one find this matter i afraid my husband find that how can i stop this man in the way he doesn't bother me any more and also with out informing others
