I'm torn on inviting former co-workers to my wedding. I worked there for several years and most of us were more like family. It's a department of about 13 people. Of these 13, seven I definitely want at my wedding, three I'm iffy on, and three I'd rather they not come. I don't think they actually show up since they didn't come to another co-workers wedding earlier this month, but I don't really want to risk it. Do I need to invite everyone from the department? Also, I'm concerned because the venue is pretty small, about 100 seats, so I don't really have any extra space.
