One thing you cannot do is have healthy human relationships without being a forgiver. It is simply not possible. A lot people do not understand what forgiveness is and I want to help you with that. If you are going to create a successful marriage then I strongly encourage you to learn.
When I say "professional forgiver" I mean that you understand forgiveness AND you have practice it long enough to where you can do it effortlessly and quickly. To some, that may sound unrealistic. It's not. The truth is, without forgiveness you will not be able to build anything worth living in.
Do whatever work you need to do so that you are not the kind of person that holds on to injuries your partner causes. I'm not saying that it is easy, but it is very necessary. Forgiveness is not about "letting them off the hook" because the hook is actually in you, not them. Harboring unforgiveness to hurt your partner is like drinking poison and expecting the other person to die.
If you are going to create a successful marriage, you must become a professional forgiver. It is a skill and you must develop it. Save the image below to your phone so you can refer back to it often.
