Probably the hardest part of healing from a divorce from a cheater are the lingering emotional wounds from that marriage.
You have to find a way to ground yourself in reality. This reality is a reality NOT defined by the cheater or her people. It is reality, in other words.
That is hard to do when you have spent so much energy trying to “win back” the cheater. Such work means engaging in their distorted reality about the marriage and–even more damaging–YOU!
The important thing to do to heal is to focus on the truth. Do not allow others to steal this from you. You can choose what you believe or do not.
It is true that she cheated and lied for months.
It is true that God considers that enough over which to end a marriage (see Mt 19:9).
It is true that godly Christians understand that truth.
