Am I being groomed?

So im (15F) he’s in his 30s (wont disclose his actual age for privacy reasons) he is super respectful and kind I’ve got no red flags from him like I know the age gap ain’t exactly good or legal but he’s so sweet and doesn’t seem like he’s talking to me just for my body so idk if i should stop talking to him or not

(Please be brutally honest)

Edit: Yes he’s sent me dick pics, I’ve told my mom she don’t really care, I came to Reddit cuz that’s all I had

Update: thank you to all the people that where genuinely worried and actually helped I’ve blocked him and have deleted all his contacts unfortunately I have no way to report him I wish I could thank you all so much I appreciate it a lot
