M.-
I am so sorry to hear that you are in such an unhealthy situation. I can't believe that the counselors that you have gone to haven't helped more. You are not losing your mind. You are not psychotic. He is and he is deflecting. He is clearly jealous of the kids and acting out. This is the time to focus on your kids. They will be out of the house soon enough. That doesn't mean you can or should ignore your husband but that doesn't like you are anyway.
My first inclination is to question whether or not he is having an affair. Sometimes when men cheat, they treat their wives at home horribly. This inlcudes making excuses for why he is doing it. Example: 1) He is telling you that you no longer have time for him. He would be cheating b/c you don't make time for him. 2) He is telling you that you don't make him feel special. 3) He continues to ask for a divorce. Cheating when you are splitting from your spouse is always easier to rationalize. Then again, "not getting affection" is also an easy thing to rationalize. So, I would look into this further.
Getting help from a woman's support group is definitely a good step. Continue to tell yourself that you are doing the right thing and that he, for whatever reason, is the one who is acting up. You sound very rationale to me and like a very good Mom and wife. Don't let him put you down. Don't let him make you feel less of a person. Just remember, kids would rather be from a broken home than in a broken home.
I hope that in the coming days, you can find a support group and that your friends and family will help you through this. I hope that you are able to have the strength to stand up for what you believe in and against his negative behaviors and actions. I hope that he can come to see what he is doing to you and his family. But most of all, I hope that you are safe and able to find peace.
Best wishes.
