Any comfort/advice/being told to give my head a wobble is appreciated!
I have been with DH over 3 years, he has 4 children between 5 and 12 years old. The children and I have a wonderful relationship, partly because I think I was very patient in the early days and have now sort of carved my own role in their lives, not mum, (who.is still in their lives and we get on), not a parent, and they appear to love and care for me very much, as I do them. I do a lot for them and I think have managed to so far strike that difficult balance between providing and guiding them without stepping on any toes or overstepping when it's not my business.
When it's DH's birthday, I get them all a present each from them, as well as a card they all write together. Last DH birthday the eldest and I went out together and got him stuff 'from' her but that I bought if that's makes sense. No problems with this and we all enjoy doing it.
Today is my birthday
I have never had even so much of a card from them that my DH has organised and, whilst I don't know for certain yet as I haven't opened any presents, I am almost certain I won't have even a card from the stepkids. Not through their own fault of course, but AIBU to think DH could have bought a £1 card and got them to write something in it?
I feel like I sound like a child but I can't help but feel a little hurt that after all I do for them and how much they appear to care about me he doesn't think that I deserve at least that. I also think it's good for the kids as well, hence why I always get them to write their own card and 'Reasons we love daddy' 
Just feeling.a little sad, like I'm not worth the thought.
