What to do about this creep?

ok i think this guy is a bit of a ladies man or he thinks he is even though no one else dose i think you should tell him that u don't like him in that way and that u never will so he should just stop while he is ahead tell him that his behaviour is not acceptable and u are not a peace of meat here for his taking and his actions are making you uncomfortable if that that dose not work tell his to **** the hell off and i really think u should take his girlfriend to the side to tell her what he has been doing and don't rub it in her face she really needs to know :D
