How you frame the issue directly impacts how you will begin to address it. It all starts with your mindset and heartset.
If you come at the issue from an angle of collaboration or from revenge, you will come up with very different ways of dealing with the situation.
Before trying to address the underlying issue, check in with your mindset and heartset. Be honest with yourself. Are you in a good place right now to be thinking of resolutions?
Are you in a loving (albeit challenged or hurt) mindset? Are you mostly angry? Is your ego in the way? Are you thinking about what is best for your marriage in the long run?
