Stella, Give yourself some time -you just found out H is living with OW and you will experience many emotions. Try to not let H see/hear the negatives you are feeling. Heck, I still feel anger which I sometimes direct at H but it is completely counter productive. I am getting better at dealing with it.
I just came across an interesting article online that suggests infidelity is due to a chemical imbalance in the brain and that the affair is a way to correct the imbalance but becomes an addiction. There is a biochemical craving for connection. I know my H told me when things started to spiral out of control that he was seeking connection with someone and he didn't feel we had that connection (part of his rewriting our history). There may be something to this theory. The author claims that 98% of M can become happier once the issues are dealt with. Very interesting!!!
