Grudges and boundaries can often be perceived as similar — but they are so very different from each other.
Grudges are a form of punishment. It is constantly holding something over another person’s head, not letting them recover for a past failure, it is not accepting that people can grow and learn from mistakes. Grudges are toxic to relationships. We are all human beings, meaning we are all going to do things that others are not ok with at some point or another. When a grudge is established it leaves the other person stuck, unable to recover from that action or actions that injured the relationship in the past. It is a lack of forgiveness and acceptance.
Grudges often lead to burn out because they are established by internalizing strong feelings and not determining solutions to move forward. It is like stepping on a piece of gum and not being able to move forward without that bump on the bottom of your shoe. A boundary is wiping that gum off, accepting the evidence that it was once there, but moving forward without that bump.
Maybe your partner forgot about an important dinner which left you feeling upset and hurt, a grudge would mean you are always bringing it up every time a dinner is planned and you are overwhelmed with worry that he/she/they will forget. A boundary would be telling your significant other how upset you were, finding out what happened to them and why they missed the dinner and then figuring out how to make sure it won’t happen again. Maybe they need a morning reminder, or an alarm on their phone, whatever it is work together to solve the issue rather than tucking it all away.Grow and learn together and you will be making your relationship stronger.
