My cousin.

at least he isn't chasing the year 8 boys around.

i don't think there is anything wrong with it though as long as the girls are comfortable with it.

My brother is in year 10 and if he got really friendly with a girl only a year older than me, I would tell him there's something wrong and tell him to be careful about the girl, especially in your cousin's and yours position :)

I really wouldn't worry about it! At the end of the day you have to realise that if they are happy together then it wouldn't be right to split them up.

I understand you say it doesn't bother you, it must bother you if you are seeking a solution. Is there another family member you might be able to speak to about it?

Hope everything works out! x

There's only 2 years diff between them not 10 geez
