Ok ... here's the plan ...
You orchestrate the next Saturday afternoon that you can spend together, and you turn it into an afternoon of ring shopping, thusly: Get in your mind which stores you want to take her around to, and pick her up at 11:00. Have some fresh flowers for her, and don't tell her where you're going. Pick 3 or 4 different shops in different places around where you live so that she'll have lots of different things to choose from. After the first place, take her to a nice lunch, after the second, stop for an ice cream, and when you're done, take a pretty drive somewhere romantic and find a quiet place to have dinner. Make this a day all about her.
By the end of the day, this is what you'll have accomplished: She will have picked out 3 or 4 favorites (for which you will need to take copious notes - get a business card from whoever helps you, and write down the style number, her size, the prices and everything so you don't get confused or forget which place had which ring. Take pictures also.) You'll know what size ring she wears. You'll have been able to speak (discreetly) with a finance person at each store to find out prices, and credit terms, interest rates (VERY important on a purchase this big), and everything else you ever wanted to know about buying an engagement ring, but were afraid to ask ... and she STILL won't know which ring you're going to be giving her, because she told you her 3 or 4 favorites.
I'm telling you ... if you do this right, it'll be a day neither of you will forget. She'll tell all of her friends and her folks what a wonderfully romantic guy you are, and you'll be letting her know that you ARE serious in the best way you can without actually giving her a ring (which you WILL do at some point shortly ... talk about anticipation!!!!)
If you want to take your relationship to the next level, this is how you do it. This is the stuff that 'your grand children will hear this story' is made of.
Now, go shopping !!
Best of luck to you both
