My nephew has this really weird crush on me. He is 8 he told his other aunt that he likesme because I'm cute smart an that I'm his type lol. When he sees me with a guy he gets mad an writes down the dates an times.
I tried explaining to him that I'm too old for him an that I'm his aunt but he saya he can like whoever he wants.
How can I het him to stop. Its weird knowing that he thinks of me like this I can't even hug him now.

An 8 year old crush probably means little to nothing... if he were 12 - 13, I'd be a bit more worried. Seems like it's more like a territorial thing for him rather than an actual attraction. I feel like it's just a phase that'll pass. As for now, can you talk to his mother or your parents to see what can be done?
