I'm sorry, I understand the loss. My jw joined up a number of years back and it was sheer hell. No one on either side knows any jw's so it was quite a shock to all the families. Mine does go to holidays and hangs out with my family but then again if he didn't his life would change quite profoundly and not in a good way! People cannot understand the losses within a marriage when a spouse becomes a jw. The trust, friendship, secret language of lovers, sweet stolen moments are gone or rare, time just plain time with them, their authentic self goes into hiding and becomes an unexpected pleasure when it surfaces (sad, shouldn't one be able to be ones authentic self all the time or at least with the love of your life?), knowing full well you are now #2 in their life as all things jw reign first, I could go on but it will just depress me, you know pretty well the changes that will come. It can get better and you two can enjoy time with each other again. If you are going through hell keep going, you gotta come out the other side eventually.
As for children? absolutely not, no way in hell, over my dead body would my kids ever step foot in a kh. Hang tough on that one. You can see the psychological damage the borg does to children everyday by reading what the ex jw adults have difficulty with on a daily basis now on the boards. (not to mention the medical & physical safety worries)
