I need advice (Urgent)!

[FloridaGreek]

I need advice and I have no one on my campus I can ask. Here is the situation: I am fraternity pledge. I recieved a few bids and I took this one in the beginning of the semester and I am now a good way through my pledge period. We are a small fraternity on my campus (30 brothers, 15 pledges). The brotherhood in my chapter is completely different from what I had expected. The brotherhood is split into two distinct and non-agreeing factions. Many of the brothers do not show up to any events or present a good role model for the pledges. This has worn off on the pledges and has caused the new incoming class to just perpetuate the already ongoing problems. The group is not strong and is not what I was looking for when I rushed. Last night I was unable to sleep. I just kept thinking that I am not truly happy. I am fairly involved in what I do on campus and most of the group is not at all involved. I have taken this whole process very seriously and I am very torn right now. I cannot make a serious or material change to the brotherhood, I have tried and I will lack the votes needed to do anything when I cross. I am thinking about de-pledging. What happens if I do? Can I pledge a different house? I have gone this far, should I just take my letters that I have worked hard for? Am I allowed to talk to other houses? I need advice. I know this sounds like a "rookie" question, but any response would be appreciated.
