Hi, have posted about dh before and have received helpful advice.
I'm posting this here and not in step-parenting as at this stage I can't understand his behavior as a partner.
We have read books on blending families and attended a year's worth of couple counseling a few years ago. I have learned to detach and not go fixing things that are not my concern, and dh has adhered to many pointers from professionals. Still... I can't shake the feeling I am a replaceable playmate, specially since the dsc are grown up.
We've always made an effort to find hobbies, interests over the years to create a sense of "coupledom", given we didn't have a honeymoon period or any together time pre kids. So even though I don't "own" these activities (we like a change every few years) I do feel put out that dh is more than eager to either include his dc or go off and "do" that particular activity/ interest with them without me. Sometimes it's really laughable! But not in a funny way.
And it's not like dh/dsc don't have their own likes and interests to share, I'm only too glad to let them have their special bonding time. I would consider myself rude to butt in (they would make a point of not letting me anyway).
My dc is also grown up now, I love having the odd lunch or chat to catch up. But would never dream of suggesting an activity my dh and I have "discovered" for ourselves. And dc would think I was being weird!
I suppose, despite marriage, I don't feel acknowledged as a "real partner", given that sex and paying bills can be had with a roommate, fwb kind of relationship too.
We have had this particular conversation before, me feeling like a roommate in a commune, and that was why we started making a conscious effort with activities...
I will definitely bring this up with dh when I see him again. He is presently visiting ILS with dsc over Xmas.
I'm writing this down to clear my head basically and hope that someone can offer suggestions on how to tackle the problem.
In my heart I know at best it's not malicious, at worst he's a man child and not fit to be with an adult woman.
