I really need help! My fiance's cousin's daughters are going to be in our wedding. The thing is- their parents are not together and their mother has a boyfriend, who my fiance and I have never met. I want to invite everyone's significant others, but this is really complicated. She lives in his parent's house with the kids and he has his own place. Who should sit with his parents? and where should the kids sit? My fiance has informed me that having a kids table is not what's done at his family's weddings. Instead, people are seated by immediate family. Should we invite her boyfriend of would that make things awkward? HELP!
