Purple Heart Vet get his kids back

My boyfriend was injured in combat by a roadside bomb in Iraq. He suffered a Tramautic Brain Injury defending our country. He has 2 beautiful boys. His ex-wife is withholding his children based on his PTSD and TBI, though he's never been abusive or anything, but a wonderful father with injuries. There is a court order in place for him to have visitation with his boys and she is avoiding the court order. We have spent almost 10k on trying to get him his boys back. His custody trial is coming up and we are barely making it with all of the Attorneys fees. He says "the only reason I lived through being bombed in Iraq was my 2 boys" we are now in the fight of our lives, all because he has PTSD. I am personally asking for any help possible to help us fight so he doesn't feel that his combat and the things that haunt him daily take his kids away. His boys are his best therapy. We need help to continue the fight.
