I think KAW is right on the money, the last thing you want is to have a big R talk and have H think thats what he's coming back to in three weeks - could be a huge stressor for him before/when he returns.
For me, I need to see the impact of R talks the next few days after and waiting three weeks to see a reaction can get your mind spiraling out of control in a bad way.
He may just need some space and this trip could be adding work related stress that has nothing to do with you and your R but yet is making him a cranky you know what.
PS - first post ever, but thought it was important to chime in
