Honestly I think it totally depends on the woman. Me personally, my husband asked me in the most romantic way possible. It was a day like any other and he came directly from work, got down on bended knee while I was doing dishes and pulled out a ring. I totally did not expect it and that's what made it so special. Some girls like you to go all out, take them out to a fancy restaurant and ask on bended knee or drop the ring in their wine glass. I think that in order to be romantic you simply must know the girl well enough to know what they consider to be romantic and fulfill their dreams!
What's something that makes the two of you think of each other? Like ... Where have you been together? Or where have you wanted to go together? Consider how public to go-does anyone need to be involved but the two of you, or does she like junbotron proposals?
I had champagne roses on my boat went for a ride anchored up to a pole in the bay and got on one knee and asked her to love me for the rest of my life . I nailed the champagne cork to the pole so when we go back every year it's cool to see.
