Uncle sent me a full body nude!! Help!!

Alanna

Okay so he is married to my moms sister and we're a pretty close family but I've never been too close with him. Always kind of got a weird vibe. My family hugs and gives kisses goodbye but I've never even given him a hug goodbye. Well today I woke up opened my snapchat like I usually do in the morning and had a full body nude from him. Then he sent me a message on snapchat that was like no no no. don't save don't save. delete delete delete. I literally just woke up so was kind of in la la land and was confused if I was actually seeing this so I never did end up saving it to show my aunt. Just curious if I should tell my aunt about it. like I get he probably didn't mean to send it to me but my name starts with an a and my aunts starts with an m. So I'm just curious like maybe he's sending other woman these pics that are not his wife? Help!!!
