In my experience you are describing viraga, the state which arises after our attachment to the aggregates fall away, leaving a sense of detachment, but nevertheless clearly comprehending the unsatisfactory, impermanent nature of phenomena.
As I mentioned in a previous post to you, if you can become a bit detached from the aggregates prior to doing the vipassana, it becomes a lot easier and there will be less suffering caused by attachment to the aggregates. I believe those who are attached to the aggregates have the most amount of suffering when they are going through this stage- when they are still fighting the insight (which is forcing them to let go)- this causes suffering. After insight wins (yeah!) then there is viraga. This is a calm acceptance that anicca, dukkha, anatta is real and is here to stay- and there is no point fighting against it.
This 'revulsion' (perhaps a bad translation) is not an aversion, but a suffering caused by craving/attachment.
We do not develop aversion towards samsara- there would be no escape for as we would be clinging to something called nibbana (ie- it is attachment to a concept). It is merely a deep (dare I say) 'intellectual'- wisdom oriented/understanding of unsatisfactoriness, rather than the development of an aversion. It is this wisdom-insight which cuts the clinging to the aggregates. Aversion cannot cut in that way- it can only suppress, push away or head in the opposite direction. Aversion will take you from point A in samsara to point B in samsara (because it doesn't like point A..). It cannot take you from Samsara to Nirvana.
Imagine a paper stuck to a tire, falling away, after the stickiness dries away (lets just say..). This drying process is the process of insight-vipassana. What falls away is the aggregates. What 'remains' (the dark tire) is nibbana.
