Dear Dáithí: I've given up drink and my boyfriend and friends are giving me grief over it

Dear Dáithí: "I'm doing things like walking the local greenway, while he stays in bed hungover. We both in our late 20s, I feel it's time to get serious about our lives. He goes for one or two pints most evenings. Weekends, it's a lot more. I feel we have nothing in common anymore."
