My take on the mediation thing, you can go as slow or as fast as you want. If you are not ready to be "done" then don't mediate any more. This mediation is volunatry and it takes "time" to come to your decisions. Take as long as you need until you feel confident "the end" is what you really want.
Some mediations take years to resolve - just saying in case you are freaking out by some imaginary deadline of mediation sessions.
