She sounds like she is looking for a "trophy husband" which is fine and dandy if the guy is a idiot and doesnt really know any better. But, you seem to have a lil bit of class to ya.

so it might not be the best deal for you.
Dude,
If you go back to her, let me know... I will fly down and chop your balls off and hold on to them for you until you are man enough to wear them again.
There are a few things going on here.
1. She is testing you... seeing how much you are willing to do for her. I.e, "How much do you love me baby?"
prediction: Highly unlikley
2. She is honest to goodness just confused, weddings are a big step and she feels a lil bewilderd by the fact that she will never date anyone else again. Mostly, it is men that feel this way, I am surprised to hear a woman feels this way too. but hmmmmmm... she strap one on every once in awhile to get the ole man testosterone going?
Prediction: Possible
3. She is unsure of you. Unsure that you are "the one" little girls dream about. She just doesn't know. She wants to go out and test the waters. Your role in this scenario? Sit back and wait for her to make up her mind. Nope, sorry dude, you can wait for her to make up her mind on what color shoes to wear with the new purse, or even what jeans make her look fat... but NEVER wait for her to choose between two (or more) guys.
Prediction: Most likely
A question my chief and I used to ask my guys when they came telling us they wanted to get married:
Johnny seaman: "Sir, I want to marry this girl"
ME: Why do you want to marry her?
Johnny seaman: Because I love her (bat your lashes and hold your hand over your heart now too)
BUT THAT IS THE WRONG ANSWER!
the correct answer is:
BECAUSE SHE LOVES ME
Bottom line is, you subject yourself to this game now, it can only get worse.
How are you gonna feel when she comes back and says "yea, you win" and then on your wedding night you are consumating the marriage knowing that a few other boys have also test drove this car?
