Inviting an ex to your wedding can be touchy. You need to be comfortable with your guest list, so be sure to discuss the possibility of inviting exes openly. Just because your fiance remains friends with a past girlfriend doesn’t mean she should be included on your big day. If an ex happens to just show up, we don’t blame you for looking enraged, but simply have someone show him or her the door. Don’t let an unwanted wedding crasher ruin your day!
