This week's question
I've been living with my girlfriend for two years in a one-bed flat. She's still in love with me, but I no longer fancy her. The mortgage is in my name, but I can't afford it without her £350 a month. If I finish it, I'll be left with a flat I can't afford and can't sell. Is there a way out of this living hell?
