May i know how did one actually forgive your parnter infidelity and how to move on?

Is this the first time? Are your kids till very young? Are you able to be financially independent? What is the reason behind this(not spending enough time together etc)? Is he willing to end things and put family first? Personally i have seen the damage a divorce can do to family especially the kids. I would forgive if its better in a whole for the family to stay together.
