Getting Children Back from DHS

My question involves child abuse or neglect in the State of: Oregon

My children were taken from me because of "threat of harm". I have been in a long term relationship with someone who pled guilty to a charge of attempted sex abuse. He spent a bit of time in prison and my children and I are very close with his family. There are of course multiple reasons why this all came about, but trust me when I say I did not let there be minor contact with said person. DHS came in and said it was inappropriate for me to continue this relationship. I had been told by the victim in the previous case that nothing had happened.
What do I do to get the kids back? I have a court appointed attorney, but the attorney couldn't even make it to my DHS appointment. The attorney still hasn't been given discovery and my children have been seperated and one is now 3 hours away in a different part of the state.

You appear to be telling us that child protective services took your children based upon your involvement with a convicted sex offender, and told you, "If you want your children back, break off your relationship with the convicted sex offender."

The answer to your question, "What do I do to get the kids back", would thus appear to be to break off your relationship with the convicted sex offender. Which relationship do you value more?

I broke off the relationship. DHS is saying it doesn't matter and that they will not return the children to me. What is my recourse?

When was the conviction?

How long have you been together?

How old are the kids?

We met in 2007 and brought all of the children into the relationship (made it public) in 2008. He had four and I had 2. We spent weekends at his parents house and he was in college trying to finish his degree. His conviction was in 2009, he did his time and got out. I have not had my children around him, there were 2 accidental contacts when my sitters brought them back too soon...the children are 9 and 12. And there is a psychosexual threat assessment from DHS and Sex Offender Treatment therapist that says he isn't a sex offender.
