Their dates were going well - really well, in fact. But Lena feared the new man she was seeing might end things when he discovered her age.

The pair, from Norway, had been going out for a few weeks after matching on a dating app. But Lena hadn't listed her age on her profile because she didn't want suitors to make assumptions or discount her.

"When our relationship became more serious, my worries got worse," says the 45-year-old. The man she was seeing, Kjetil, had already made it clear he was looking for love rather than a fling.

On their first date, Lena told him she had a teenage daughter, but that didn't put Kjetil off. He just assumed she'd had her when she was young.

"I actually thought she was maybe only a couple of years older than me," says 30-year-old Kjetil.
