ummm he might want to marry you, that is so good! but don't get your hopes up it might just be he wants to buy you a nice ring for your birthday or christmas, but just don't be surprised if he asks you.
You already know this one. You're just excited about it, so this is your way of telling other people! If you were honestly that clueless, I feel sorry for the guy. So instead of telling you what it means, I'll say congrats. Good luck to you, and Merry Christmas.
