The dream: You see your W as a wild fox, and want to catch and tame her!
As for the out of town weekend, don't let your mind go there. My wife has done 3 vacations on her own (or with a GF) since bomb drop. (the first one was extremely hard on me)
She emailed me everyday, (we don't have/use cell phones) then comes home and shows me pictures and tells me all about her trip in a manner that I know she couldn't fake. Since you guys are getting along good and playing around together, I wouldn't be surprised if your W did the same thing.
Show her how strong you are while she is gone.
M: A really long time. Crisis: 5 years. She's still worth it.
Life is never made unbearable by circumstances, but only by lack of meaning and purpose. -Viktor Frankl
