What rights do I have for shared property and a home I partly paid for/still paying for but the deed is not in my name?

It,is never wise to purchase mutual real estate prior to a marriage. Married couples share the marital home as a "tenancy by the entirety" which means both can claim ownership even if one is not on the deed.
In your case your own claim to the home is a constructive partnership which is difficult to prove because you have no document formalizing your equity in the home. Your receipts for furnishings, your checks as to mortgage and utility payments, are all paper proof of your claim to a shared equity. Another way to look at this is you cannot afford not to hire a lawyer even if it only to review your papers when you see what you can lose in regards to the equity in the house. You might be able to sue for a forced sale, but without your name on the deed that will be difficult.
