Hello Faithful Wife,
I identify with the emotional turmoil you are going through, albieit from the other side of the fence. You see, my wife, in her defense, felt that the pressures of our marital problems was too much to handle emotionally. And I now don't fault her for that.
At the time, though, my life-long JW programming of staying in the marriage "at all costs" was strong,strong,strong. And as a consequence, I probably ended up pushing her away in various ways that I wish now I had not. This was partly due to my feelings of righteousness as a result of "sticking with it", regardless of the harsh realities of my marriage.
Yet, marriage is a very simple and very complex thing at times, and while there is much virtue in trying your damnedest to make your marriage work, I have also learned that sometimes love (or the desire and need to "be in love") is not enough to make it work.
All I recommend is that you have a clear conscience. In other words: Make sure YOU have a "relative" peace with the hard decisions that you will make.
Also, only YOU know YOUR circumstances. I also realize that the need to vent your feelings here (as I have done and am still doing) is quite natural and needed.
However, I have a word of caution: With all respect to our female posters here, while having your feelings validated is a very human need, please be wary of any "group-think" reactions and advice to divorce. I am sure that they sincerely mean well, but this is an emotionally vulnerable time for you, and only YOU can make this assessment of your marriage.
Regardless, whatever the outcome, please be assured that you DO have people who care for you and will help you get through this. I know this because it's happening to me.
Please take care of yourself,
Bourne
