Grief does affect different people in a variety of ways. My childhood friend and myself, are like two polar opposites in how we've grieved losing our moms. My bf is similar to myself, yet, I'd venture to state that I talked even less about it, than average. Yet, his childhood friend and myself, both from what I've been told, kept pretty tight lipped, about our mom's after death. Three years, later, well, almost four now, I am more apt to mention her, more often, than I had. Did I love her, terribly? Yes. Miss her? Yes. Did she and I reach a peacefulness, in her death? Yes. This could just be your husbands way. Is this, a bit of family tradition, for him? A learned reaction/behavior? Is this, just the way, his family grieves?
It hasn't been a year, yet. If, after the one year anniversary, and this is a daily repetitive pattern, perhaps, then, would be a good time, to have this talk, with him, about revisiting the counseling topic.
My concern, for you, is the dismissiveness, of the monthly 'date night.' That's important.
Congratulations, on your soon to be, new family member, your child!
