Sister, I am sorry it has come to this. I may say some things here that may hurt, cause you to think, or make you cry. But I feel in time, it will help.
Obviously, this did not happen overnight. This has gone on for some time, at least a year Now this will obviously bring to question what has transpired over & during that time and what did you do to repair it? What has he done? BTW, how old are the children?
I will tell you this, to make the children write negative comment about there dad is unfair to them unless he is verbally or physically abusive. I found this our second hand. It sucks, and the kids would resent you later for it. If the marriage in irreparable only bc the 2 of you are not willing to work it out together, then you have 2 choices only.
Stay, for know ye not that he may be saved by your belief, and your children be stronger for it. You would be blessed for it, and so would your family, tho it will not be easy.
Option 2, you would have to leave, and my guess, due to the emotion I sense, it may get pretty ugly. The kids if young will take it hard, and you will split up the family...actually, to clarify, you both would. He is very much at fault as well.
Now, think back for how ever many years you have been married. When did you first start to sense a change in him? What was going on in your marriage at that time? Was he ever really involved in church? Did the two of you have a fight? Lose a job? Lose a loved one? Go impotent? What? That is for you to answer.
Once you know that, you may have an idea why he is drifting off. Do the 2 of you still talk? Do you converse? How long has it been lacking if so? What was going on then? Same time? If different, what was different?
Pray for God to heal your heart and to let you see what is causing this. Ask Him to open your eyes to see without personal interference. Ask Him to see your husband thru His eyes. And pray often for your husband. 1 min per hr. minimum.
I am not saying it will be easy, and as long as he is not abusive or adulterous, try to stick it thru.
In our prayers,
MM
PS, just got word of some of the history on this one. WOW is all I can say. May God comfort you in these times, and may peace and joy thrive within you always!
