Hi all,
So, my bf and I have been talking about getting engaged for a while now, though I'm not sure when exactly (that's his job

) and we've even looked into rings and some other basic wedding planning.
Here's the rub, while his parents (both sets) are very alright with our plans and even know of them, my parents don't know at all. They know we're dating and they aren't too keen on that so I can imagine how they'll be when they find out we're getting engaged.
If anyone had a difficult time telling their parents they were getting engaged, I'd love advice on how you managed it! I know, with my parents, they don't feel I've lived enough life, at the wee age of 22, to really know what I want in a husband. I know they'll make the "you're so young" argument and there will be the "he's not good enough for you" vibe going on too.
I want to tell them soon, so that when my bf asks for my hand, which is a tradition he and I think is very necessary, they won't be completely caught off guard.
It's difficult because I have a feeling that my parent will be disappointed and I hate disappointing them, but this isn't a decision they can make for me; I know who and what I want, at least, in my bf!
Any advice or helpful comments would be much appreciated.
