We know that it certainly is not physical touch. She loves to talk, so I would guess that quality time/communication is her primary language. She also grew up poor and in a totally dysfunctional family with no Dad. I think that she may have married me to get financial security. We are not poor, but the securtiy is not always there. She also wishes I were more ambition, meaning I think she wishes I would get more job advancements and make more money. So would this be acts of service? She also wants me to do more with my kids, and she wants to see me do more with other guys.
