The man, identified as Nicholas C. Nelson, 48, of Parkland, told the woman "you and I, we die together" in just one of the messages investigators say he sent.
According to the report, the woman only knew Nelson through a close friend, but had only met him in person several times and had rarely spoken with him.
The woman told investigators the messages began on April 5, and that the volume of messages escalated after she told her friend about them, hoping to deter Nelson.
Another message sent to the woman, according to the report, read: "The only man you'll ever be with again is me."
But Nelson's actions went beyond text messages, according to detectives, when he sent the woman a threat and also left clothes in the front yard of her relatives' home.
Nelson also had an aggravated stalking case reopened in Palm Beach County from 2011, but the details of the case are not immediately available.
According to the Sun-Sentinel, Nelson told a Broward judge that he felt his bond was very high and that he doesn't feel it should be that high. His bond was set at $500,000 and the judge told him that based on the allegations, the court believes there is cause for concern.
