I have no experience in these matters
, but it shouldn't be the way in which you propose that matters; that much seems clear to me. If she truly loves you for who you are then she'd recognize the fireworks aren't necessary. If the way you proposed were to bother her at all, then she doesn't feel that way about you and it wasn't really meant to be in the first place; the proposal itself shouldn't ruin anything.
As for her response... Hmmm, maybe I'm outta line here because I don't know her in the slightest but I'll give some possible scenarios...
1. She has kind of committed by taking the ring, but she isn't sure what to do still... She's trying to work stuff out in her head. The fact she took it is a good sign, as if she wasn't interested at all I doubt she would've taken it. Maybe the whole "opposite sides of the world" thing is weighing on her mind, maybe she's just trying to work out her feelings. It's odd it would take this long, but hey... Chicks
...
2. Maybe she wasn't sure you were serious (as was mentioned before): I don't know how long you were dating or anything etc, etc so it's hard to tell why that might be (for example have dinner with her twice and asking her to marry you will get you some giggles friend
) but that would cause the noncomittance.
Does she wear the ring when you see her (or was she when you saw her last) because that'd be a good sign obviously... If not... Eh...
I don't know man... Just throwing stuff around here cause I'd like to give you an answer and help a brotha out, but I don't know anything about you guys. What's been said about communication you guys obviously need to work on, but that's ok: nobody goes into a marriage having everything worked out perfectly. Confront her about it in person and be assertive about it: get an answer if you have to lock her in the room with you.
Anyways I doubt any of this helped but good luck to you friend
