Thanks, Grizz.

My wife will sometimes talk and sometimes not. When I am on trips, she doesn't communicate with me very much at all. I guess I probably take her silence personally. I am working on that. I think we both notice the difference in our interactions with each other, hence the "weirdness". She seems to want things to be "familiar". Maybe she feels that may help her "love" for me come back. Or she could be just expressing her distress. She says she really doesn't like change.

On your input, I'll continue contact, but hopefully with no expectations. That way, I'm not trying to control her. I will also remind myself that I am in control of my feelings and thoughts when I do communicate with her.
