I need your help!!😫😫

Okay so last year I ment this guy, let's call him Vincent. He's my neighbor and well I had feelings for him at the beginning but we never actually talked. So I just ignored him and stopped thinking about him. BUT then 2 weeks ago, he got a mail but wasn't home so  they gave it to me. Later he came for his mail, and he was joking and idk what,(the first time we actually talked) I was kind of happy but didn't put my hopes high. 
Yesterday, I was walking with my mom, and I saw him coming our way, he was smiling at me and offered us icecream. 
Please help me idk what to do😒 I feel like he likes me but not sure, he seemed a little shy before but since we talked that changed. 
Any advice will help, I wanna talk to him but idk what to say
