Take the lady - or the man (who says it is only a man's job to take the lead?) - to a locale where the senses can feel all that is beautiful and wonderful in this world. And that is when you should whisper - or shout - how you want your future together.
There is always time for short, periodic getaways. Work is just a means to an end. Have the will to travel, and it will happen. Nothing can or should hold you back.
