We’re obsessed with our phones and we’re obsessed with relationships. Vicki and Geraldine talk to the academic who studies how one is changing the other. 

Talking points: 

• When you’re watching TV and your partner picks up their phone, should you put the television on pause?
• Back-burner partners: how technology is encouraging us to keep our romantic options open.
• Facebook is increasingly cited in divorces. Has it become too easy to cheat?
