The solution to just about every relationship problem is forgiveness. Forgiveness is the ultimate love weapon - use it often!
Manasseh the King, did great evil towards God and yet when he humbled himself towards God, he was forgiven.
God's Word tells us to forgive our neighbor and the most challenging neighbor we have is ourselves. God forgives us and remembers our sins no more. We are to forget the past and run the race set before us enjoying the heavenly prize of eternal life.
