I think it's a normal and kind thing to do in the circumstances. They were a family before you came along and you knew that. If they wish to bond for the odd day and remember their mother I think that is lovely for all of them.
You are with your DH every day and for 25 years, can you be generous of spirit and realise that other people have needs and feelings too. I think you are being over sensitive and selfish to be honest.
I knew a couple who married after the mans wife had died and she was so jealous of his son [in his 30's] that the marriage fell apart. She was being utterly ridiculous and controlling.
I had a stepfather who would never, ever leave my mother and me alone when I visited her. So we could never reminisce or discuss family business [which badly needed sorting out]. It was awful for me, I begged her to tell him to leave us alone sometimes as I felt as if I had 'lost' my mother. He did for 2-3 times but relapsed. So please think of the daughters feelings in this, they lost their mother at vulnerable ages and she was so young. They have accepted you for 25 years and show your gratitude please. The scenario could be very, very different.
