Dunleavy's denial of the offences was "devastating" for James.
"It's as if we're still telling lies, because he denied it.
He says he has forgiven Dunleavy but it is a constant process.
"To forgive him was the only way to get rid of it, it's the only way for me to carry on.
"But it comes back, it doesn't last - you can forgive him in the morning and want to kill him in the afternoon. It's a thing I have to deal with day in and day out."
James says he believes there are people who suffered at the hands of Dunleavy who haven't come forward yet. And others who haven't made it.
"l have got friends in the graveyard over this, that didn't get the chance, that weren't able to cope with the mental load and buried themselves in drugs and alcohol and weren't able to get through it."
Dennis said he wishes he could have done more to stop Dunleavy.
"There's a lot of guilt there because you did not speak up and it's only now you're finding out about the amount of people that's come after you," Dennis said.
"You've that guilt there and it lives with you every day, that if you had have opened your mouth and said something maybe it would have been nipped in the bud."
"Back in them days priests, brothers, all of it, they could do whatever they wanted, they got away with it.
"It's only now people are finding out what they were really like."
