That means he has no heart to show that he loves you.
Your not a failure, you did your part. Why should you listen to your dad? What about your mom? Has she been there for you more then your dad? Yes (Im sure of that). Your getting married, you should be proud that you decided who you want to walk you down the aisle. Your dad doesn't make the choices for you. You are a grown woman, and we have powerrful words. So if you love your step dad, since he has treated you like his own daughter, you have the rights to consider him as a person giving you away. Nobody isn't stopping you hunny. Let your wedding dream come true with out any problems. You are doing a wonderful job. Dont let your dad put you down. Get married, be happy, enjoy life. Dont let your dad walk over you. Thats not right.

I had my father in law give me away (just married that time he did) becuase my adoptive dad and I weren't getting along. My adoptive mom wont go if my dad showed up. And my adoptive dad wont go if my mom showed up. It was a mixed up world for me. So I decided to call my "soon to be father in law" to take me down the asile and that did safe my stress cause I was 3.5 monhts pregnant that time.
