Greetings. I am sorry to hear about your separation, but glad that you signed an agreement.
If you did not negotiate for him to maintain you on his health insurance in the separation agreement, then he has no obligation to keep you on the insurance.
If you signed your rights away and signed a quit claim deed, then I doubt you have any further rights to the house. Now, if he was hitting you to make you sign the agreement, then you may have signed it under duress. Signed (and notarized) agreements are rarely overturned by the court.
Best of luck.
