Just wanna jump in and say I so can relate to the obsessing thing too. My mind would just start thinking about it when I'm free, and I happen to have much free time at the moment. I also messed it up by talking to my H about R and saying that he needed to end his affair....turned out...to be really bad for us. Well, just want to give you some support, I'm trying to figure out what to do with mine... good luck!
