Hi Justin,
We haven’t walked in Anna’s shoes, so it would be unfair to pass judgement. It is possible that Anna thought Josh molesting his sisters was in the past and he was now reformed. Even his sisters had forgiven him and moved on. But Josh was deceitful and led a double life . She again gave him a second chance after the cheating scandal came out. This time around with the arrest, it is a very serious offense. It changes everything. Hope she makes the right decision for her family.
