You are better off keeping your son close so that he knows he can come to you if there are problems
Every week Annalisa Barbieri addresses a problem sent in by a reader

A year ago, our almost 18-year-old son began seeing a girl, who is a year older than him and is his first ‘real’ girlfriend. Soon he stopped seeing his friendsand he spent all of his free time with her. When they were not actually together, they were on the phone or playing remote video games.

We barely saw him over the summer, as he was with her all the time. He refused to go on holiday with us unless we invited her too, which we were not willing to do .
