I know I'm really young to even be on this site, but let's have a little introduction, just so you know where I'm coming from.

My boyfriend and I have been dating for little over a year. We know that we can't imagine our lives with anyone else in the world, and he honestly means the world to me. I'll be 18 and a half when he turns 20 in December. We're both in college, both freshmen. Now don't be alarmed, we know that it would be basic nonsense to get married DURING our time in college, and we are going to wait to actually get married until after we've both graduated. It's hard enough being a student, and planning a wedding and being 100 miles from home at the same time? forget about it.
Now what I really wanted to talk about is my parents. I know that once my bf purchases the ring, he wants to ask for my parent's blessing. Notice that I said blessing, and not permission. My parents know me and they know I can be a real individual. My boy and I will still get engaged, but we would prefer to have my parent's blessing. As for his parents, they are ALL for it. I mean, his mom even lets me call her mom. And, well, his stepdad goes by his name, but still. His parents I'm not worried about, and he has talked to them, so it's not like a big surprise to anyone.
I know I'm going to have to talk to my parents face to face about this, but even with all that reasoning about being out of school when we actually get married and his parents' view and all that I'm still really worried that we won't get my parents blessing. And I don't want to have too much bad blood between my soon-to-be fiance and my parents, you know?
Thoughts? Suggestions? Magical potions and or spells? (haha, had to add SOME humor...)
