Crissa Franceschina says Ingrid Lyne met John Robert Charlton, 37, on a dating site and she had told friends about their upcoming date to a Seattle Mariners baseball game last Friday.
"There was some trust involved obviously [between] her and him," Franceschina says.
Franceschina says Lyne didn't tell her a lot about Charlton, but she believes they had been seeing each other for six to eight weeks.
Lyne was a devoted single mother who was focused on children and her career as a nurse at Swedish Medical Center, Franceschina tells PEOPLE. Following her divorce from the father of her three daughters in 2014, she began looking for romance online in her scare free time.
"She was busy working and was kind of dating off and on," Lyne's friend says. "Obviously the girls, were her main focus and kept her busy."

"I was worried immediately and sent out [Facebook] messages to our friends. We knew she went to the Mariners game, we knew she was with him," Franceschina says
Investigators discovered several dismembered remains that they believe belong to Lyne in a recycling bin outside a Seattle home on Saturday afternoon. Police and the FBI are still searching for the rest of Lyne's body.
Charlton is being held on $2 million bail on second-degree murder charges in connection with Lyne's death. He is scheduled to make a court appearance tomorrow.
