I did not grow up in quite the same situation as what MIGHT be the case for you and your boy(s)(?).
But, my parents D'd when I was an infant. My mom re-married (2nd of 4th H for her - yeah, I know, issues, but this is your thread) and my step-father adopted me. No one told me until I was 12-13 that my step father wasn't my father. (Yeah, more issues).
My point is, although I formed a R with my biological father and had a good R with him until he passed away in 2003, it wasn't the same as the one I had/have with my step-father. In fact, I don't even think about my step-father as my step-father. He's my dad, b/c he's the one who raised me and who has been a father to me even after my batshi$ crazy mom D'd him. HE was the one who coached my little league football and baseball. He's the one who stood on the sideline with me at my high school homecoming football games. While I knew who my biological father was (and spent time getting to know him), my step-father was and is my Dad.
Biology isn't important when it comes to emotions. If those boy(s) think you are their father, THEN YOU ARE. And I don't give a dam# what a DNA test says. Don't lose sight of that. They will need you.
Not trying to make you cry (although I can feel a lump in my throat- maybe it's getting close to my time of the month....sorry).
