Hi Wishful thinking,
one month! (thinking about it !) And he does not come along! (!) He must feel terribly worried! And envious. And afraid what you do! And what if something happens to either one of you You having a good time and he is suffering :'(. Poor guy. What do the neighbors, colleagues and family think? How will he cope when something comes up? He is rightly frightened
There is plenty of stuff to validate... . (see related workshops). Also SET can be used:
S: Oh dear
E: it will be ... . (hard, awful, etc)
T: being apart for some longer time will be a real change and not easy for us. At the moment you feel blue and there will be times too where I struggle too. But it is the plan and we need to stick to it. And when getting together we will appreciate each other even more.
Have a clear plan when to communicate (adhere to it 100% on your side).
And enjoy your time away
