Q. An ex-boyfriend is confusing me. Recently he's been dropping hints about how much he still likes me and when we met up we ended up sleeping together. In the morning he acted like nothing had happened and later emailed me for advice about a woman he'd met. One minute he says I'm like his little sister, then he says he thinks about me all the time and wants to be my 'prince'. My friends think he's messing me about because he's 24 and I'm 19.

A. This guy is being controlled by organs that are lower down and more impulsive than his brain. Don't hang around waiting for him to make up the mind he isn't using. Go out and meet people, and keep your options open. Don't sleep with him again because every time you do, it will start you hoping for what he can't give you - a relationship. Five male years in the teens and early twenties aren't the same as five female years. He has to mature a few more before he can be taken seriously - or take himself seriously - as a partner in love.
