can anyone help TT TT

soo, I have been best friends with (lets call him Z) for about 6-7 years and ive known him since sixth grade. We bonded over games like Tekken, Persona, Mario Bros, Space Invaders and our houses were pretty close to each other so we hanged out a lot. We went to arcades, had frequent walks around the neighbourhood and went to the nearby park and bought Halo-Halo (filipino dessert) or ice cream most of the time when we were hungry. Though, he dropped high school for sum reason and wouldnt tell me abt it, we were still in touch.

Back to the present. Z and I met occasionally when we had time. Just a few days back, we went to a quite fancy-fancy restaurant. I didnt think much of it but he suddenly confessed.. saying he liked me because of my personality and how naive I am and how he doesnt care that we are both boys. Z has been messaging every few hours asking about my health, how ive been doing, if I ate well, or just whatever since the confession and idk what to do, im not experienced with this type of stuff and dont know how to proceed,,,
