Most of us will never be faced with such a dilemma, but many will make sacrifices for love.
Anya left behind her family and everything she knew after meeting Duncan at Glasgow University.
Anya, a pseudonym adopted for clandestine communication with Duncan, grew up in a strict religious family in Glasgow.
"A relationship based on love was just not an option in my life. Or so I thought," she told the BBC.
Meeting Duncan changed everything.
"I had never realised how trapped I was."
Anya resolved to leave home and pursue the relationship.
