Narrative:

I was (arm) vectoring air carrier X toward the base leg, descending from 8000 ft to 3000 ft. At 4000 ft I saw that the spacing on another aircraft being worked by arf was going to be close so I left air carrier X wbound and told him about the traffic. I also informed him that he might go through the final. At which time I saw air carrier Y (arf) being vectored by arf controller. I asked arf to turn the aircraft. He informed me that air carrier Y was sebound and no factor. At the time I felt this was tight but not an operational error. 6 days later I called the facility and had to ask if I was decertified. At that time I was told I was decertified.
