Maybe one of the administrators can move it if you ask them to or you could re-post it for more replies.
You will need to give more details of what assets are involved for someone to help. The main priority will be housing everyone but you mention multiple properties so presumably this is already done?
Although it sounds like children are with you majority of time an 80/20 split in your favour sounds unbalanced unless it is the only way children can be housed. Who earned the most during the marriage is of no relevance, all contributions are regarded as equal.
Because you were married, which in its most basic terms is a contract which obliges you to share everything with your spouse. You may not like this, but I''m afraid it''s the law. The only time in which contributions are not considered to be equal as a starting point of negotiations is when one party has behaved particularly badly ( maybe committing fraud).
