If AV doesn't pass, will there keep being referendums until Lib Dems get what they want?

Or will this be it. It looks as if Lib Dem and AV support is slipping fast. If AV passes, will this actually help smaller parties or pretty much keep things the way it is? I don't think it is a democracy unless you have FPTP. The fact is there are going to be smaller parties. If a party is small, it is because people are not interested, plain and simple. If this passes and it causes the lefty or loony's, I will remove myself from this country since people are so hell bent on making this country into something that it is isn't. Ireland, Monaco, the Channel Islands, and NZ really are looking good at this point.
