I sometimes have similar fearful thoughts when my T travels. I have to remember that they are just thoughts, they the thoughts are about my own fears of her going far away from me. It seems the farther she goes the greater the worry. When she went to Europe .. I had worry thoughts about her safety, thoughts that she would fall in love with some place over there and decide to retire and move there.
Strange as it sounds, these kinds of thoughts are ways of staying connected while she is away. I also am able to just simply miss her while she is away without constructing these scenarios that are nothing but my imagination and that frighten me.

chicken wing, I hope you can have some peaceful thoughts of her, miss her while being curious about what she's doing, feeling happy for her that she's vacationing and enjoying her time and at the same time she is still connected to those back home and looks forward to returning when vacation time is over.
