A woman who sent a man she met online 65,000 text messages after their first date has defended her obsessive behaviour by saying she did it because she didn't want to lose him. 

The 31-year-old Phoenix woman, who faces charges of stalking and harassment, allegedly flooded the man’s inbox with up to 500 messages a day.

She said she met the man on an online dating site and felt she had found her “soulmate” after the two went on an initial date.

"I felt like I met my soulmate and I thought we would just do what everybody else did and we would get married and everything would be fine," she told reporters.

Her obsession reportedly took a darker turn after the man called police on her after finding her outside his home.

Court documents allege that after the incident, the woman’s text messages turned violent.

"Oh what would I do w ur blood! ... Id wanna bathe in it," she reportedly wrote.
The man called police again when he discovered that the woman had entered his home and taken a bath there while he was away on holiday. When police arrested her, they found a large butcher’s knife in the passenger seat of her car.

According to court documents, the woman told police she had no intention of hurting the man but kept texting him because she did not want him to leave. 

She now faces charges of threatening and intimidating, stalking and harassment, and is being held without bail.
