How do you get to the point in a relationship where you absolutly know you want to marry this person and not know if they want the same thing?

Looks like the band is no more...

Bad move! Not a good idea to do this to a girl. Intimate strings are the way to go, especially if she isn't an attention lover.

It could of been worse, she could of said yes and then tell you no later so you would have to explain to everyone what happened, still though that really sucks

Yeah making a big show of the proposal doesn't go well. A quick search online and you can see the # of videos where it went wrong. The sports one particularly, a lot of people do not like being put on the spot and feel huge pressure to say yes or be thought of being a mean/bad person by friends and family for saying no. Big showy proposal only works if you are absolutely sure and you have to consider the persona's personality and whether they'd even feel comfortable being asked like that. A lot preffer something quiet and romantic .

.. Could have been tears of joy eh?

If she ran off crying, she obviously wasn't ready, and he probably either didn't talk to her about it before or only saw what he wanted to see. As humiliating as it must have been for OP (and believe me, he does have my sympathy), any time you put something that personal out in public, there's a chance it won't go well. I think that 99% of the time, public proposals just put undue pressure on the person being proposed to and turn what's supposed to be a beautiful moment into a performance.

That was a sweet idea though!

It seems like a lot of you are overlooking the fact that she's in a band. I doubt she had a stage fright moment. And stop pushing your preferences onto others. Not everyone thinks it should be a private thing. I'd love it if someone put the effort in to make it a big deal. You just have to know what your partner would prefer and be sure he/she would be okay with sharing the moment with a ton of people.

Your music must suck
