you don't have to reward her for having an affair and you don't have to worry how she will manage after you are divorced, she's an adult, allow her the ability to be responsible for herself, she made adult decisions, chose to have an affair, chose to split up the family and you are still trying to take care of her and be the nice guy, stop that and be the "real" guy, let her deal with the reality of the situation, let her put on her bgp's (big girl panties) and deal with reality just like you have to.
