Walk away spouse- what else can I do?

[Handler]

Yep, I could have handled both of those responses better.
Learning sometimes involves hard work. I've been told I need to keep my expectations low so disappointment doesn't occur. You may also be right (again) Sandi that she may have invited me to go the beach, had I not responded with having "work to do."

Things do appear to be on the upswing despite my sliding briefly yesterday.

She asked my opinion on a couple of decisions last night and we worked together to sort out some childcare scheduling. She smiled at me during a couple of the exchanges and we're having some eye contact when we communicate- these things are a definite improvement over a month ago.

I hope I'm not grasping at straws by viewing our interactions as positive signs...

She called and left a message today wanting to know if I delivered the kids to their childcare, and also to ask my opinion about another issue. I'm going to call back but I'm making sure at least an hour goes by before I do.

I like the things that I'm seeing but it turns out I will probably need to leave town for about two weeks to help my mom who is having some serious health issues and lives a long ways away. I need to do this and will probably leave by the end of the week but I'm very concerned about losing some of the momentum that seems to have started after 2.5 months of 180 work. Telephone and email contact will be sporadic at best for me after I leave.

How do I approach this and keep DB'ing?
