We’ve all got at least one friend who, when they’re single, is keen to meet up, go out and spend time together. But as soon as they start dating someone, they suddenly drop all their pals like a basket of hot potatoes. Regular get-togethers are neglected, phone calls go unreturned, you hardly ever see their face at church – it’s like they’ve been abducted by aliens. Until, that is, their relationship breaks up or starts going south. Then, suddenly, they’re back wanting to hang out – until the next time they meet someone. Do you have a friend like that? Or – let’s be honest – are you that friend?
