I NEED ADVICE #TRIGGER WARNING sensitive content( Mentions of SA)

Soo.. im being groomed online and I am afraid because I told him what city I am from and looking back on out messages he fantasizes about meeting with me and doing things to me im under 18 and he is in his 30’s Im scared hes mentioned that he was actually not too far from my city. I feel embarrassed because how much I trusted him I thought I was in love with him because of sweet he was and he would always tell me how beautiful I am. I never really even gotten attention from guys like he gave me, nor even had a boyfriend, he talks about my virginity.. just a lot. I told him what university im going to because I was so excited and we talked about me stressing which college to go to a lot. Im not on the campus yet ill be a freshman now im so scared, Im scared I could be stalked now or possibly kidnapped or r worded. I dont know why I did this to myself. A part of me still likes him we did talk about sex and I liked it in the moment but now I dont know how to feel. What do I do
