If you plan to propose in Bogota, do two things:

1.- Speak to a shrink or anyone else capable of talking sense into your head.
2.- Hop a flight out ASAP before you ruin the rest of your life.

That "Angel" you are about to propose to is wearing a common disguise that foreign men are 99% unable to see through in Colombia, but one thing will be clear - you will be taken for the ride of your life, no matter how angelic she seems now.
