Does he have feelings?

so me and this boy have been just 'friends' for about a month now, or two. I was perfectly fine with just being friends. 
but we occasionally have sex. he calls me baby, baby girl. calls me every night, comes over and cuddles for hours. met my parents, just chills. & he says I love you to me. I've met his family & all his friends. gets jealous if I hang around other boys, talk to other boys and what not. but we're still just 'friends'
 I'm not sure if he has feelings. someone tell me how they know if a guy has feelings!! 😩
