<human>: We're keeping our wedding really small. We aren't inviting all our extended family (aunts, uncles, cousins) or all our friends. Small. 

I of course invited my best friend, but made sure to address the invitation only to her, with no plus one anywhere on the invitation. 

She knows how i feel about her asshole boyfriend. She's tried breaking up with him before, but he always weasels his way back in. This last time he went to her church (even though he doesn't believe in God) and convinced the pastor to call her and tell her to take him back. When that didn't work, he showed up to her church with a gift bag. ..with lingerie inside. Ew! It's church! I've met him a few times and before i knew any of this he already made my skin crawl.
 

I realize i can't control who she chooses to date, but i absolutely feel like i shouldn't have to have anyone at my wedding who isn't welcome. I don't want him there. 

The worst part to me is that she didn't even talk to me about it, just went on our wedding website and rsvped for both of them

How do I tell my best friend I'm not comfortable having her asshole bf at my wedding, without jeopardizing our friendship or coming out looking like an asshole?

Give me the gist of the text in a nutshell
<bot>: i don't want my best friend bringing her asshole boyfriend to my wedding, but unsure how to resolve the situation without affecting our friendship.
