Divorce Care is EXCELLENT for those getting divorced. However, because this post is addressing "separation", I think it's important to note that not all separations end in divorce. When I was separated, I always made sure I acted like I was still married (because I still WAS married). During the separation period if you are both talking, I think it is essential to get professional outside help if you want any hope of resolution. I also feel there are many wonderful books and resources that could be invaluable to you. And book by Willard F. Harley (I especially like "He wins, She wins" and "His Needs, Her Needs." Or go to Gary Smalley's site Smalley Institute - Reignite your marriage in two days or Family life's weekend to remember site: Weekend to Remember®. ANY and all of these could be really helpful to you.
I did end up getting divorced and benefitted from Divorce Care greatly as I went through that process. It seems like you really want to work things out and I sure hope and pray that you can do that.
Good luck to you!!!
