I have a strange question to ask and I know how it is going to sound but stick with me please. My girlfriend's younger cousin has a crush on her and I was wondering if I should say something about it to her or just ignore it. He is only thirteen and I met him for the first time yesterday. When we were alone he told me Mandy was his girlfriend, not mine and he was going to marry her when he grew up. I laughed at him because I didn't know what to say but it is a bit disturbing.

At thirteen he shouldn't be having feelings like for his cousin and he should probably be talking to somebody about them. I have two female cousins and I never had any feelings like that for them when I was younger. Just the thought of it would have made me sick. He hugged her four times when we were there and Mandy was very friendly with him. I'm not jealous or threatened but I am concerned about his wellbeing.

Has anybody else on this forum came across a scenario like this and what do you think I should do? Is it natural for a boy his age to have these feelings? I was surprised she had a cousin this young but there is apparently a ten year age gap between her Father and her Aunt.
