Even if she let you "come back," you will still have to deal with:
"The organization, the elders, the WT, the AW" will always be telling you what to think, what not to do, what to do, how to do it, how to feel, how to breathe.... The Borg creates a terrible extra burden on any marriage. Guilt is a prime ingredient in any WT recipe.
I have seen the grandmother of an abused child fight for the Society one day, yell at the Society the next, go back the day after, and smile and breathe and then shun her sons because... now she gets to 'be a pioneer' again. Quite sad, but quite true. My point is that the Society has an uneasy, uncanny power over people, and they don't even show natural affection any more...
It's better you start over younger, than go thru all kinds of MORE misery, and have to start over older. Number one, find out who you are. Love yourself, find things you really really enjoy doing. Move, get a different job that you can get to know different people at. Get a different perspective. For as much as people think that there is "only one person" that is your ideal match, that just could not be true! If your ideal match is in the same town you were born in, and mine too, etc, etc.... Well, what would be the odds that it is simply looking for a person, getting to know a person, then coming to appreciate and love them? There are many other great people, allow yourself the chance to live. :-)
Hang in there.... life changes one step at a time.
