If your husband is there, sitting like a bump on a log, you're going to set up camp, take care of the kids, cook, supervise and be unhappy....no angry.
If your husband is not there, you're going to set up camp, take care of the kids, cook, supervise and have a great time.
What's the difference? Hint: It doesn't have anything to do with your husband. It's all about your attitude.
I'm not even sure if detachment is the right work for breaking that cycle of negative thinking that just keeps building and building and building.
Let it go, if you can...go and have a great time! Because camping is fun, right?
