Akron, congrats! I wish you all the best. My H has been home a week since moving out almost a year ago. It has been a long haul, but worth it.
Please do let the FF go. My FF's husband spends a lot of time with some FFs and she is very hurt by that. Even though nothing is going on (at this time), she feels that she is less important than they are. Her insecurity, I know--but just can't see anything good coming from us having close friends of the opposite sex.
I look forward to following your progress--good luck and best wishes!
