The post that struck a chord with me is by HunterFox:
One thing I have found out that does work is emulation. I have quietly tried things that she is now into and briefly asked her with mysterious out of character for me questions that I would only ask if I was doing the same things she is. Then slowly over time the bonds on the same things are getting stronger as well as the interaction of conversation. These things are my way of at least getting her to feel comfortable talking to me about things irrelivant to the marriage, trying not to slip in the occasional "marriage question" as it relates to the topic is hard at best. I have shown taken great interest in a soap opera she likes and we have long talks about the storys, at least we're talking and we share laughs and smiles with each other as the conversation about it goes on and I apprach her with zest and zeal about the storys lines from the day before.
By taking a direct interest in something she enjoys immensly has opened quite a few doors. It also has made her occasionally touch me without even thinking about it and calling me things like "honey", "sweetie" and others during our comforting banters.
It may be a baby step but it is definatly a solid firm step and it works for me.
How I stumbled across this little gem of an action is that I figured out something she has a deep enduring passion for (the soap opera) and figured out that if I take the same and deeper passion for it she would open up and we could talk more, the rest of her actions are bonus icing on the cake.
I've been wondering if I need to develop more of an interest in cars, NG is mad about them.
