Narrative:

Reading approach was busy on this day. I was monitoring approach frequency and at 15 DME southeast I called them with my location, altitude and intentions. They asked me to call back at 10 DME. Upon calling back at 10 DME I was given a squawk code and asked to identify. After my call another aircraft called at 10 DME east approximately 2 mi to my right wing. Level with me. Approach also gave this aircraft a squawk and then vectored this aircraft towards my position. They asked him to descend to 2200 MSL. I was at 2800 MSL. They called traffic to him (me) but never informed me. He informed approach that traffic was in sight. I climbed to 3200 MSL to avoid being closer to him as he passed directly under my aircraft. Rdg approach never called this traffic to me. I did see him from the time he first called his position to approach. At this point I was now 6 DME to rdg airport. Approach handed me off to tower. Before leaving approach frequency I informed approach of my dissatisfaction with their handling of me. Upon landing approach controller called me to apologize. I am familiar with this airport and feel that they should have rted traffic to flow better into the airport I feel that one of us should have been vectored in a way to allow for more separation than what took place. Had I not been paying attention and the other pilot not fully aware of what he was doing this could have been a catastrophic experience!
