Hairdog, I really like the way you speak of your wife in this post, and the attention you give to the fact that she might receive love differently than you do.
I went and looked at the 5 LL web site to get an idea of what you are talking about. This book does look worthwhile. I guess I'll order yet another book ;->
So your question seems to be, "how can I make acts of service and quality time romantic, so I can enjoy them too"? Is that the right place to focus?
My wife is big on "acts of service" and "words of affirmation", but mainly wants acts of service. For me to feel like I'm giving a gift, it seems to work best if I am creating something lasting and fun, like the giant swing set that I made, which had to be adult size so we can both swing on it and talk, but also gives our 6 year old something to do with the neighbor kids so my wife can concentrate on other things. (It wound up 16 feet tall, but you know how male overexhuberance works). Hmmmm....it's about time we spent time swinging on it again.
I wish I had been able to make the coat racks she wants before she started doing it herself (I was out of town for 3 weeks during the last month, it was a bad time, but I'm also often behind on chores, and she winds up doing more than her share). Coat racks feel like a way of welcoming people into our home, something we both value.
So what would make your house more of a home? Is there anything that lets you serve by creating a better environment for the two of you, or a home that is more welcoming to guests and family?
