The 39-year-old mother, who was originally from Japan, allegedly got in a fight with her husband Carlos Salavar shortly before leaving Salavar’s apartment in Bay Ridge, Brooklyn, on Nov. 8. Salavar told NYDN the couple, who were married in 2014 after meeting via social media, were arguing about child care issues and the cleanliness of their apartment.

Salavar said his wife called him from his mother’s apartment 10 days later — the last time she was seen on Nov. 18 — and said she was ready to reconcile. He said her plan was to take their son to the library and then reunite with him, but she never returned.

“I spend most of my time running around Brooklyn,” he told NYDN. Just hoping I’ll see her. Just to see if my boy’s OK. She didn’t take anything. No winter clothes. No diapers. That’s what scares me the most.” Salavar says he reported his wife missing on Nov. 18 and the NYPD confirmed to PEOPLE that the case is ongoing.

Salavar said he has not been able to reach her and she is not responding to his text messages, according to NYDN. While she was on Roosevelt Island with his mother, Salavar said his mother expressed “concerns about her.”

“My mother started telling me, ‘I think your wife is depressed. She wakes up late. She doesn’t do anything. She doesn’t take care of the baby,’ ” said Salazar.

Salazar also said it’s possible his wife worries about him taking their son away from her if they get a divorce.

“She has this idea that we’re trying to take him away from her, but we’re not,” he said.
