hi, i went through the same thing with my ah a few yrs ago and i did have the bond revolked. even though they did not run out and pick him up, i was glad that i was no longer worried about being held responsible for his actions. turned out, he had relapsed being the reason he went awol. hope thats not the case with your rabf.
if you really are afraid of him being a flight risk, you may want to think about doing it regardless. otherwise, i believe sometimes emotions can cause hasty decision making. i'd say take a few deep breathes, think about your motives then do whats best for you. keeping you and yours in my prayers
