My (long) Pledging Story at a Tennessee University

[KiwisRugby]

I went through rush this fall with an open mind and had my interests narrowed down to 3 fraternities when the preference nights arrived. There are 8 IFC "national" fraternities at my school. There were 2 days of formal rush and then 2 preference nights. I narrowed my preferences down to the 3 (XYZ) that gave me the strongest impression on the formal nights because of how well I got along with the actives I met and talked to, as well as the ideas they stood for and how the actives talked about them. I attended 3 different preference events for two fraternities (X&Y) and ended up having so much fun at one particular house (X) I lost track of time and missed an event for another fraternity (Z). At the end of the night my heart was set on X and when I received my bid the next morning my hopes were realized. I began pledging and enjoyed every aspect of it, but there was one thing that would end up causing trouble for me down the road.
Money had never kept me from relating to and getting along with people; it was the same with this group of guys. I lived in the dorms and the rest of the pledges lived in new apartments, but it didn't bother me. I drove the oldest car out of all the pledges and actives, but I had to work for what I had and I was proud of it. The dues looked formidable, but with a job they were possible. I learned that it was the pledges responsibility to pay for materials around the house i.e. cleaning supplies and anything that had been forgotten by the actives when we planned our parties and social events. My pledge brothers and I would all chip in for stuff like this so it was never a problem. I didn't mind contributing for the good of their chapter because I hoped to be a part of it someday. So far, so good...until I learned that I was expected to buy illegal drugs for some of the actives. I thought this was just a test and when I found out that they were serious, I was in doubt about everything that had made me want to pledge (X). I talked to my pledgemaster and he said that I didn't have to buy them but the actives were still pressuring me. I was real torn up about it, but I decided to quit almost a month into pledging because it was becoming evident that this wasn't the place for me.
I am thinking about going through spring rush but I have many questions and doubts. Is it possible to pledge to another fraternity the next semester because things don't work out? Would another fraternity even want me or would I be considered as "left-overs"?
