One of my fiances groomsmen's girlfriend wants to come, but heres the thing. One of my bridesmaids dated the groomsmen before. They have no problem with it, but I know the groomsmens girlfriend will try and start something on the wedding day, she cannot keep to herself. Do I invite her, as we used to be close, or not invite her and avoid the problem for my big day??? And I know if she doesn't come, than we will have to hear about it from her boyfriend, the groomsmen...I am completely lost!!!
