So I feel a bit hurt but you need the background to understand and tell me if you would feel the same. My DH is my 2nd husband. His 1st wife died v sadly at only 39, his daughters were 16 and 19 at the time. I met him a year later, my sons were slightly younger, 14 and 16. We have been together now 25 years, and I get on well with my step-daughters, we all get on well with each other. Last year the girls decided they wanted to take their father out for a day on his own, just the 3 of them, to "make memories". I was a bit hurt but bit my tongue (one of my superpowers), and they had a nice day out. Now they want to do something similar, this time on Mothers Day next month. I understand them wanting to "make memories" with their dad, but to me it feels rude, I would never have dreamt of deliberately going out on a special day out with my sons, and if they'd asked, I'd have said no, it would be rude to do so. Mother's Day is fine as I will make a plan to be with my boys and their families, but after all these years, I suddenly feel like we are 2 families again, not one. Part of me says I'm being over-sensitive, and part of me just feels hurt and excluded. FYI there are no problems between DH and myself, and I haven't even hinted at my real feelings about this.
