Hi Lois. If you have a chance to read my old threads you will see where my H fell off the face of the earth. Like I and our kids did not exist. Went from living here, to packing up leaving and never calling or seeing us. I initiated every attempt to see him. Maybe wasn't always the right thing to do on my part. He went 3 months with no contact with his kids. This is a man who loves his kids dearly. He was miserable, ashamed of himself, and depressed.
He was also drinking heavily prior and during.

We are R! He has been home almost a year and things are good. Not easy but I am glad he is here and so is he.
All I can say is listen to the advice of the vets. What they say is true. I took a lot of repitition for me to listen. But they are right.
Y0ur H is not himself right now.
We too have a child with special needs. I think that plays some part in their conflicted minds.
Take back your power.
I know it is so hard to watch someone you love act like this and treat your kids like this. I know exactly how you feel.
Make the best life you can for you and your kids. You will never regret doing that.
I will check back soon.
