“My parents’ promise to me meant nothing” – Dr Louise answers your burning questions

I’m madly in love with my brother’s friend who is three years older than me. They’re at university together and I’m in Grade 12. The problem is this guy views me as a “little sister” and obviously doesn’t think of me in romantic terms.

What can I do to make him see that I’m grown up now and am in fact a woman, not a little girl he can pat on the head and make jokes with?

I’ve tried to persuade my brother to take me along with them on a night out so I can dress up and make him see I’m not a kid anymore but my parents won’t allow it and my brother also tells me I will spoil their fun.
