I offended my girlfriend's Christian parents. How do I fix this?

It seems like she is way too good for you and you don't really deserve a second chance. But, If your heart is set on trying, so be it. You need to prove Erika that you will change, get your act together and get a better wardrobe ( THAT IS NOT FLASHY STYLE. I WOULD BE DISGUSTED TOO). Send her flowers, ask her out on a date in the card in the bouquet and make it a nice evening date. Dress modestly. Jeans with a tucked out polo would be nice. But somehow i could see you trying to incoorporate "batman" into your attire just stay safe. Don't do anything that may offend her in any way at all, and be charming. Don't bring up the night at her parents until the end of the date and just give her a heart felt apology
