Happily married, expecting, freaking out

I am wondering your take on this.  I happily married.  I could not imagine my life without my wife.  We recently found out we are pregnant and I am extremely excited about it. But recently I have been having troubling thoughts.  Before I married my wife I had close friendships with two other woman.  We were extremely close and I thought I would marry one some day.  It was one of those close friendship that had unspoken feelings but you could tell were present.  We were young at the time.  Mid college and never had and opportunity to date.  Then we graduated and we went our separate ways. I moved away from then and our relationship grew distant. I then met my wife and she was amazing.  I decided I wanted to spend my life with her.  I have had no regrets with marrying her.  But recently I have started having dreams about these two other woman from my past.  Maybe it is just me freaking about becoming a father but it is really bothering me and I do not know what to do. I have ignored my repeated dreams and now random day dreams for a couple weeks but it is starting to bother me. I feel I might have some unresolved issues and would like to move past it and stop having these dreams.  Has anyone else experienced this or have any advice?  How can I finally close these chapters of my life?
