Stepdad And Daughter Song

I am about to get married in about 19 days and i still do not have a song for me and my step dad. He came in to my life after i got out to high school. I really do not see him that much or talk to him. He is my step dad but the thing is i do not put him as a dad. It is hard for me because he really was not in my life when i grow up until i was out of high school. If anyone can help please let me know. Thanks
