Yes, there's a relationship between soil staying too wet for too long and the amount of time it takes for it to 'go bad' on you- the reaction where the lime neutralizes acid from the peat happens in aqueous solution; basically, if your soil is wet all the time you are going to see your pH drop faster, the roots will not be able to uptake nutes also because they need oxygen, and the particle size of your medium will also break down.
It's easy to avoid this- re-pot into pots only SLIGHTLY larger each time, so that you don't end up with whole soil zones that the roots can't access and therefor jsut SIT THERE wet and stagnant when you water.
