Should I Forgive My Back Child Support Arrears Case

My ex is $186,000.00 in arrears. He fled the state when trying to be served divorce decree. I was granted final divorce after 3 attempts to serve. He said because he did not agree to divorce, he does not feel he has to pay child support. He has evaded the OAG for 8 yrs and has even assumed ID theft with his brother's info.

He is laughing at the courts and the OAG because they can't find him. Now, he wants to travel and has asked I do a modified order to forgive his arrears and he will pay me $5000/mo for 24 mos. and then $1500/mo until the youngest is 18. He said he would also pay $600/mo in support until the boys are 18. He will not disclose his location or phone number to me. He only emails via his blackberry phone.
Should I trust him?
