My mother was married several times too. But the only one I really cared about was when she and my father split up.
After that, they were just step fathers who didn't really amount to anything in my life.
Her last husband (present now) is a very good man, but I was already married with kids when she found him.
A long time ago i figured out it was about her, not me. For most of the Christmases in my childhood I prayed for my parents to get back together (I watched the Parent trap) it was not to be.
Perhaps that's a good thing.
