@Jon NTX amd Bug are both spot on... Unconditional love. I know it doesn't feel good AT ALL and no one here is saying accept or approve what has been done..
1 Corinthians 13:4-7 4 Love is patient, love is kind. It does not envy, it does not boast, it is not proud. 5 It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. 6 Love does not delight in evil but rejoices with the truth. 7 It always protects, always trusts, always hopes, always perseveres.
That's unconditonal love, but Jon you have to love yourself 1st and say that no matter what your situation your posture and chracter will NOT change based on the behavior of another. I'll say again you have been truly blessed and you don't even see it right now. This is a test...
