Jacqueline Ades, 31, was arrested in Phoenix on Tuesday on felony charges of threatening and intimidating, stalking and harassment, a misdemeanor.
Ades reportedly met the unnamed Paradise Valley resident through a dating site in 2017.
The two went out together on a single date, but Ades allegedly fell in love and began actively pursuing the man.
The victim said Ades, who described herself on social media as a makeup artist, inundated his phone with text messages, sometimes sending as many as 500 a day, reported ABC15.
Ades' love interest contacted police twice last year after she parked outside his home and continued peppering him with unwanted texts. Police responded to the area and escorted Ades off his property.
The victim said after that incident, Ades sent him threatening texts, one of which stated: 'Oh what would I do with your blood! Id wanna bathe in it.'
Another menacing missive read: 'You do whatever you have to do to get here… but don’t ever try to leave me... I’ll kill you... I don’t want to be a murderer.'
