I agree with Bobbijo - every contact you have with OW shows her just how much she has got to you and makes her feel good.
She was obviously very emotionally involved, whatever she claims about who chased who, otherwise she would never have started lending money. She is not your problem to deal with. Both you and your H should block her emails. She must have known when she lent him the money there was little chance of getting it back.
What's important is you, your H, and your children. I know the way the OW portrays you hurts....but hey....she has shown how good she is at interpreting events....look at her version of taking the high ground!!!! What matters is that deep down inside you know the truth.
STOP interacting with OW - she is feeding off the drama.
