I totally agree to that. As a wife, yes, I may appreciate efforts made by my husband and any woman would be so happy to receive expensive gifts and eating in a fancy restaurant. However, if you are already a parent, you will not think only for yourself and your partner. You need to consider the needs of your kids. So your priority will change.
As for me, may it be a valentines day or any special or even just a simple day, the thought that my husband loves me sincerely would already more than enough. A simple hug, kiss on my forehead and a reassurance of his pure love to me would be the most romantic gift of all.
