My parents don't know that we're engaged

Me and my Fiance have been dating for over a year now. Im turning 19 in July and he's turning 22 next month. He proposed to me during Valentines, and he didn't tell my parents because he wanted us to tell them. Although I think this is an ok idea my dad is an ex-marine and scares the living daylights out of me sometimes and when he's disappointed I don't know what to say im scared he wont approve. I was wondering if anyone had any ideas of how to start this conversation, what to say, and what to do if he doesn't approve at all?

1 st thing if you love some dont let no one stop from be with that person and your really care about you even if he does not like it he will be ok with it "scaring someone
will only get you so far" be storng
start with "we need to talk" tell he how you fell about (fiance} then say that proposed
and you hope he will be their for you

if your father is an ex marine, he would probably be more inclined to approve with a grand outward display of respect. you should talk your fiance into asking for permission to marry you from your father. if your dad says no, then he would have said no anyway. what a great way for your fiance to get his foot in the door... not to mention that if your dad says no after your fiance has been such a gentleman, he will either feel like an a**, or he has a really good reason that the two of you shouldn't marry. if that is the case... maybe you should hear him out. your parents most likely just want what is best for you.
