Here's a bit of history/info before I get to my question.
My BF of 4 yrs and I are set to get married in October, 2013. I'm African-American, he's Caucasian. My father has been absent majority of my life, and the few memories that I have are downright awful, but for the sake of releasing bitterness, I forgave him. We've shared maybe 15 emails, and fewer phone calls over the span of 4 years. During one of our phone conversations, I asked my dad if he's racist, he immediately said no, but I clearly remember him having racist conversations with his friends and spewing hate to me at an early age. I didn't press it any further, I just made note of him being a liar, among other things, and took anything else that he said with a grain of salt. (Besides, people can change, right?)
Fast forward 2 years, we're in October of 2012. I prematurely asked my dad via email if he'd be interested in coming to our wedding, and also asked if he'd be bringing any guest. I was appalled when he replied with a list of 12 people, including his soon to be wife and my grandfather, both whom I've never met. I know that it's my fault for being a bit vague, but I honestly thought he had the sense and decency to not send an entire list of people based on our history. I felt anger, confusion, guilt, and a host of other emotions, so I decided not to reply to the email until I was able to sort through all of the emotions. Well, about a month ago, I saw my dad for the first time in 7 years, and my FI met him for the first time ever (I've known my FI for 14 years). It was really awkward, and the awkwardness intensified when he mentioned the email I never replied to. He was telling me how he feels awful for not being able to pay for the wedding (my mom is paying for the venue & caterer, everything else FI & I will be paying for). I've been hearing this from him throughout my entire life, so once again, I pushed his comment aside, and didn't address the email.
About a week after seeing him, he called me just to chat, and I finally told him that I have apprehensions about him coming to the wedding. His reply was downright strange, but to sum it up he said he's okay with not being invited. A complete lie! A little later in the conversation, again I asked him if he's racist, he said yes with the exception of my FI & my FMIL. That sealed the deal, his name was scratched from the guest list, but for some reason, I feel guilty for not inviting him. I've come to the conclusion that I don't really like him as a person, and that's aside from all that he has and has not done. If he weren't my dad, I'd never associate with, but for some reason, I still can not shake the guilt for not inviting him. I do want all of my guest to safely enjoy themselves, and his presence may jeopardize that.
Am I wrong for not wanting him there? There's a lot more to the story, and I have another question to post relating to this situation, but depending on the advice that's given for this question, I may not need to ask.
