Nicola Bulley's partner has said he "will never give up searching".
It has been two weeks since the mum of two first went missing. Mortgage adviser Nicola, 45, was last seen walking her dog Willow after dropping her daughters off at school in the small village of St Michaels on Wyre, Lancashire on January 27.
Speaking to Dan Walker, Nicola's partner, Paul Ansell, said he is "going through hell". He added: "Nicky would never give up on us so we will never give up on her."

In the interview, which will air on Channel 5 at 9pm on Friday, Paul said: "But that hope and that positivity in me is stronger than ever, and I'm never, ever going to let go. Nikki would never give up on us ever. She wouldn't give up on anybody. And we're not gonna ever give up on her like, we're going to find her."
He added: "There has to be a way to find out what happened, there has to be. You cannot, you cannot walk your dog down a river and just vanish into thin air. Something happened that day, something..."
On Twitter, Dan, 45, shared a number of photographs from his heartbreaking interview with Paul. He had travelled to his and Nicola's home in Lancashire to discuss her disappearance and the search surrounding it.
As the search continues, it has now expanded to the Irish Sea. Lancashire Police launched a massive search and were seen combing the river bank utilising diving teams, search dogs, drones and boats to no avail, reported The Mirror.
Police have said their "main working hypothesis" was that she fell in a river but a body has not yet been found. However, they insist they are keeping an open mind. Detectives are also looking into a mystery two-hour gap between the mum's disappearance and the first call to the police to report her missing.
Nicola was last seen at around 9.10am and police were called at around 11am. Lancashire Police have said they are working on the hypothesis that Nicola fell into the river, but no trace of the mum has been found after specialists have searched a mile-long stretch of the River Wyre.
Specialist Group International chief Peter Faulding said he is "100%" sure Nicola is not in the stretch of river initially suspected, and his job is done. Yesterday, the search moved to Morecambe Bay as two boats with specialist teams were seen in the sea.
Anyone with information which could assist our investigation should call Lancashire Police on 101 quoting log 0565 of January 30th. For immediate sightings please call 999.
