But, there is a thing to consider. If your H sees that he is going to be hurt majorly on his long term future finances, he may pretend to want to come back so that you back off the big gun. You need to not be so easy to take him back.
I second this, Doodles. I absolutely think he may do this.
As I just posted to someone else, you will KNOW what GENUINE remorse/desire to reconcile looks like. Because you have seen the FALSE one from him before, you are in a great position to recognize the real thing if and when it does show its head.
