How about proposing to her all the way again but in style on Valentines day? You can plan for a skydiving adventure or a hot balloon ride with your wife and get a small cake cut in the balloon ride or propose to her in the sky. You can even gift your wife her favorite jewelry and propose to her once again.
On the valentine night, get dressed attractively and wear your best outfit which would be seducing. Create a romantic environment in your room with Valentines day decor and light candles. Then cuddle your wife and end the Valentine night with romance. If your wife had been in her office throughout the day, once she is back home, serve her some wine along with some snacks. If you can accompany her, maybe she would love it.
Take your wife on a drive, so that you can talk to her. You can even take her to an exotic place where you can enjoy the nature and have some romantic time in that place with her. Maybe some isolated or old deck places or beaches will be perfect that evening. You can even go hand in hand and cuddle her – She would love it!
