My dad left me when I was three, my mom and him were never married. I'm currently living with my mom and she's remarried to my step-dad. My biological dad has never been there for me and I'm sick of having his last name. He doesn't deserve to have me have his last name. My step-dad has been there for me all my life. I owes a little repsect. I'm tired of baring my dads last name.
