There is a lot of controversy over whether an ex should be invited to the wedding if he or she is still a good friend of you or your spouse. In my opinion, NO EXES! Your marriage signifies that you have both moved on, so there is no reason for you to invite an ex!
You want your wedding day to be special and care-free. Inviting an ex could result in unnecessary problems that will stress you out and cause tension between you and your spouse, which is the last thing you want on the first day of the rest of your life together!! In addition, inviting an ex could lead guests to spread rumors at your wedding because as we all know, society loves to gossip. If an ex is at your wedding, guests could suspect that you are not over him or her. It will also make your spouse happy knowing that your old relationships are 100% over as you begin a new, permanent relationship together. My best advice to you is for the sake of avoiding drama on your special day, don’t invite an ex.
