Dear K. W.
Ok, so here goes.
I am sure that you need reassurance about this situation, but you also need the truth.
If your husband is not touching you, then something is definately very wrong.
If he has a close friend that he shares things with, then talk to him and tell him about the problem, and ask him if he has said anything to him.
If not, or if he hems and hahs, then he does know something about the situation and feels uncomfortable telling you.
Now the one thing you must ask yourself is this, look in the mirror and be very critical, are you worth more than you are getting?
Do you look appealing to the opposite sex??
If the answer to those two question is yes, then Girl, you need to kick this guys butt to the curb.
Men as a general rule do not lose their interest in sex, unless they are ill, or they are having an affair, or their wives have let themselves go to seed, with an abundence of excuses. Or they have reached the age where it is no longer important to them, around 60 that starts.
And if you think for one minute that your children do not feel the tension between you and your husband, then your living in a dream world.
I personally feel that it is a big mistake to ever stay together for the kids.
I didn't do it, and it did present some problems. But in the long run, I still believe I made the right decision.
So take an HONEST look at your situation, and then you will know what to do.
My husband never wanted to have sex either, and it was very traumatic for me.
I do understand where you are coming from, and my heart goes out to you.
Just be very critical and honest, see yourself and your marriage as others see it.
You will make a good decision for yourself and your children if you are honest.
Good Luck and my prayers are with you.
