I agree with everyone else. Tell him to "travel safe" and leave it at that. Don't worry, he will be thinking of you even if he doesn't contact you while he's gone. Having said that, I have to say that a month is a long time to be away from the person that you've spent 38 years of your life with. Even teenagers that go to camp miss their family! LOL
You have seen what has happened in my sitch over the past year. From frequent trips to visit the ow to talking her into moving here to talk of separation. 2 days later, h claims that he's looking forward to being rid of the ow. Of course, time will tell but it's a beginning.
You have come so far and just like the rest of us you will be a success story in one way or another no matter what happens!
Well wishes on your surgery RL. I haven't been reading here much so I've missed the date of your surgery. Is it this week?
