Getting Over

How long does it take you to get over the concept of divorce?  I mean, we're still going through it but I'm not entirely over the thing.  I feel in shock, like I've lost someone to a death.  The only thing is that it happens over and over again, with each time that I see him.  

Right now I can't imagine having a life after this.  I mean, I can't imagine ever falling in love again.  My heart has been hurt so extensively that I'm not sure it will ever recover.  That's just how I feel at this very moment but I believe that God is capable of healing my heart and someday bringing someone special into my life again.  Even thinking about the future, my romantic future, makes me stressed out.  

My big fear is that my current spouse will remarry and his new wife will want to be mom to my children.  I am secretely afraid that I will become obsolete.  I realize this is just my fear because everyone says that I'm their mom and am irreplaceable.  I know the kids too - they are mine.
