Maybe I am not seeing it, but I have not read many here that say to not date after the breakdown of the marriage. If someone is still heartbroken or has any hope of their spouse coming back, then no way should dating be considered.
I've dated and had a great time. Sure, my current girl friend and I have reached a point where the relationship is not going any further, but we have both enjoyed each others company together. I know that we both never had an argument and that we have learned from one another.
