My husband and I have been together for 20 years now...married 17 years.  This is a 2nd marriage for both of us.  He has 2 SD, I have 3 BS.  Our youngests were 5 when we got together.  I should have known from the start how life would go but I was to caught up in my new romance, new place, divorce, child custody, child support etc. to really clearly see what was going on around me.
