I am sorry you two are still struggling. I know how discouraging that is, on so many levels.
I know you're unlikely to get my reply since you've left out on your trip already. But I just wanted to offer the suggestion that you make the best of this weekend. For your sake as well as for your H. As they say (including MWD), act "as-if". Set your differences aside and try to enjoy yourselves for this weekend, at the least. You might be surprised.
I believe in you, lady. You can do this.
Many *HUGS* and blessings. And stay safe on your journey.
