I think it is totally normal for them to pull back not just WAS's but men in general. It's called "rubberband" in men are from mars, women are from venus. They get enough intimacy and then the "pull away" and the only thing you can really do is give them space and wait for them to "spring back" it is really helping me to have that visual image in place when my hubby pulls back after a good date or a serious R conversation. So don't worry. The 3 day break is probably the best thing for both of you right now.
I would keep conversation to a minimum while he is gone. And I would also challenge you to stop reaching out with physical signs of affection when he does get home. You never seem to get the response that you want and it comes across as very pressuring. so I would stop. Let him initiate any and all physical contact at least for a little while.
Did you get an appointment scheduled with Jody yet? Now that she is back from vacation.
Keep your spirits up, there are still positives here.
