Ventura County sheriff's deputies say George Costales had been sending the woman unwanted emails for the past year.
Investigators say the woman had blocked Costales from her MySpace account "at least five different times." Then last week, deputies say Costales announced he was selling his business and moving to California to be with her, "because he loved her."
When Costales arrived at the woman's front door her boyfriend recognized him from "photos he had posted online."
Investigators said they used the Internet to lure Costales back to the woman's house, where he was arrested on suspicion of felony stalking.
Costales is being held at Ventura County Jail in lieu of $500,000 bail.
