JACKSONVILLE, Fla. – A man charged with shooting and killing his ex-girlfriend's new boyfriend before attempting to commit suicide had inundated his ex-girlfriend's phone with text messages about feeling betrayed, according to a report from the Spinnaker.

The University of North Florida's campus newspaper obtained the text messages from Jarod Miller to Lindsey Varner, who had been broken up for more than three years after a nine-year relationship.

Miller, 35, survived a self-inflicted gunshot wound to the head and has been charged with one count each of murder, armed burglary and shooting into an occupied dwelling.

Miller is accused of killing 34-year-old UNF student Nicholas Hare at Varner's home.

Varner told police that Miller continued to contact her after their relationship ended and that his attempts increased after he learned she was dating Hare.

Police said that on Aug. 28, Hare (pictured) and Varner were at her home when Miller came over unannounced, shot through the glass of a back door to get into the home and then shot and killed Hare before turning the gun on himself.

Varner fled the home and called police. Miller underwent surgery at UF Health and survived, police said.

The text messages UNF Spinnaker investigators obtained highlighted Miller's frantic efforts to contact Varner and his anger when she did not respond or take his calls. (Note: Text messages are as originally written.)

“I feel like u stabbed me in the back and u hate me,” he wrote. “But u want me to just forget everything move on never speak to u again. U really think that I diserve all this. How would u feel if our places were reversed?”

Miller also appeared to blame Hare for keeping Varner from talking to him.

“Soooo crazy u won't talk to me after all this time not ev day but at all,” he wrote. “I know u ant like that I kno it's cause of him. I know if u could make things better u would but boy won't let u.”
