Seeking a way to get my boys back

Hello. I am fighting to see my boys.. My ex-wife and I went through a big and nasty divorce. She was awarded everything even the children. Its been almost a year since i have seen them. I talk to them once a week over the phone..

But I want more. Right now they live in another state..I would like to know my rights, how i can get them back. I do have a lawyer but i don’t think that is enough is there more i can do. If you have any suggestion or ideas please help.. thanks in advanced..
