You don't say whether you are married or not, which makes a huge difference to your legal rights.
If we assume that you are married, you have no automatic legal entitlement to a share in your spouses assets on divorce. There is no way that anyone here, with or without legal training can even guess what sort of divorce settlement is appropriate in your case.
The job of the court is to ensure a fair outcome for the couple and especially for the kids in the future, depending on the income and assets of both parents.
