Cemar, people build incredible emotional connections via text alone. Long distance relationships are springing up all over thanks to the internet. People are making and building emotional connections *who haven't even met each other physically*.
How can that be, if what you believe is true?
Your wife may build emotional connection by working quietly together with you on home projects. It may be via long conversations where you both focus on each other. Her heart might swell if she observes you being a great dad with your children. Tenderness might arise if she observes you dragging your butt off everyday to a job that you don't care for in order to provide for your family.
For you, kisses = emotional connection. No kisses = no emotional connection.
For her, emotional connection = kisses. No emotional connection = no kisses.
