Engaged at 19?

Me and my boyfriend have been dating for 2 years now, and currently I’m 18. We were talking about the future and stuff like that and he randomly told me he wants to marry me. He said in about a year, he plans to propose to me. The thing is, I’m still pretty young and I’ll be 19 in a year and I don’t know how my parents would feel about me getting engaged so young!! Obviously I want to marry him but is it weird or bad to get engaged so young?
