It is easier to be the judge or plaintiff than the accused. Trying to fix your spouse won’t bring any real solution to your marriage but fixing yourself will.
“Judge not, that ye be not judged. For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again. And why beholdest thou the mote that is in thy brother’s eye, but considerest not the beam that is in thine own eye? Or how wilt thou say to thy brother, Let me pull out the mote out of thine eye; and, behold, a beam is in thine own eye?” – Matthew 7: 1-4
“For if we would judge ourselves, we should not be judged.” – 1Corinthians 11: 31
“Look not every man on his own things, but every man also on the things of others.” – Philippians 2: 4
