Do I Get A Turn?

As I sit in the waiting room, waiting, I obviously have a lot of time on my hands.  A lot of time on my hands means a lot of time to think.  Which is never a good thing for me.  One of my step-sons has just come out of surgery and they have brought him to his room.  As I, his step-mother for the past 5 years and in his life for 2 before that, wait in the waiting room, his mother insists that her best-friend and brother be with her.  My husband is in there too.  I on the other hand am in the waiting room all by my lonesome.  I begin to wonder why my husband isn't insisting that I be by his side in this particular situation.  Why am I not given a turn to be with my step-son?  It isn't like I am here for my own health.  It isn't like I haven't been there for him these past 7 years.  Why does no one think I have any rights in this situation?  I understand perfectly well that I am not his mother, nor am I saying that I should have the same rights.  I am saying that as a step-parent, a step-parent who has been very involved in my step-son's lives, there should be some respect and courtesy given to me.  However, there isn't any.  Sometimes not even from my husband, this is a prime example of that.  Everyone always says that I knew what I was getting into when I started dating my husband.  Another one is that I have two children of my own that I have to worry about and to stop worrying about the three that aren't mine.  Yes, I did know what I was getting into, but it wasn't always like this.  There is no fine print to read before entering a relationship with someone who has children with someone else who they were also married to.  When you love someone you don't think about the hardships that could happen in the future.  And yes, I do have two beautiful children of my own with my husband.  But before those two children came, there were only my three step-sons.  Three boys who I came to love very much in a very short amount of time, who I would do anything for.  Not just because I love their father, but because I love them.  They are my family.  Why does no one see that?  Why is it so hard to understand?  Why do people look upon it as a bad thing?  They have grandmas, grandpas, aunts, uncles and cousins who love them too.  Why is it such a taboo that I, again their step-mother for the past 5 years and in their life for 2 before that, love and care for them too?  So can anyone tell me, when is it my turn?
