Strict parents? Boyfriend?

(Greek is first language so don’t be angry if I don’t know how to say some English words)

I’m going to start by giving bit of background about my life:

-I am 16 and I go to all girls high school (in Greece 15-17 year old is senior)

-I have strict parents, brothers and family

-I have 3 older brothers

-Never have boyfriend before

I go to all girls school so I didn’t really talk to boys too much in persons only snapchats but I like a boy Nicos and we talked for 3 months but I can’t be dating him because my parents and brothers get angry and don’t let me but I think I am old enough to talk to boys because am 16 and my friends have boyfriends. He is senior too 17 and I like him very much but I am not allowed to dating him so how do I tell my parents that I like him??
