You did very well on the vaction with your kids and H. You both were able to see the drama coming and most of the time walk away from it. I'm betting in the past a full blown fight would have erupted. So take that as a positive.
Being apart for as long as you both have been it is going to seem stange and awkward to be together so much. You are going to go through times that it is uncomfortable and forced. Maybe instead of trying to do things that you use to do together you need to find new and different things.
You both have changed and your R has change and will need to keep changing. You don't want the old R anyways so trying to do the same stuff is only going to bring back the old R. You both need to do different things I am sure that you have new interest and hopefully he does to, explore them and see where that gets you.
Take care and try not to dwell on your S leaving and school starting too much.
