Narrative:

I was 10 NM south of ZZZ on a straight-in approach for runway 1 when I began to make radio calls. I made a radio call almost every mile. I didn't hear anyone in the pattern until I radioed a 3 mile final and another aircraft said that he was left downwind for runway 1. I made another radio call at 2 miles and told the traffic that I didn't have him in sight. He immediately replied stating that he had me in sight. I continued with my approach and when I was about 1 miles final a twin engine aircraft; which appeared to be a piper seminole; flew directly over my right wing and seemed to be on the same glide path as me. He was closer than I have ever wanted to be to another aircraft inflight. He then turned slightly right and then left again to align himself on the upwind leg. I landed and taxied back to runway 1. At the same time the twin engine aircraft continued the pattern. After he landed and was clear of the runway I took off. While I was departing the area; the twin pilot came on the radio and asked if I noticed that I was 'almost cut in half by a twin.' I told him that I did notice and the last radio call I received was with him stating that he had me in sight. He told me that I cut him off and that the FAA would yell at me for doing a straight-in approach. I told him sorry and that it was a miscommunication. I don't know exactly what was going on in the other aircraft but maybe he lost sight of me or he was exhibiting a macho attitude because he felt that I had wronged him. I know that I should have been more clear and direct on the radio and should have asked him if he was going to extend downwind for me. If he said no I could have very easily slowed my approach to allow him to land first. If nothing else; I certainly could have done a go-around. I think this all could have been avoided if both myself and the other pilot would have been more clear on what our intentions were.
