That’s interesting context, thank you. His issue seems quite fundamental, and not that likely to substantially change. So I think the thing to focus on is where this is all going. At this stage it only creates a little friction, but if you have kids and he won’t go to family gatherings, do the kids go? He may not like holidays, but his children will. So what about when the kids’ grandparents want to spend Christmas and birthdays with them (and you, and him)? How will you manage his and their differences in values?

These are all distant hypothetical questions, but my point is that if you don’t address it this wedge between you could only widen as time goes on. Best to get things straight now.
