how important is the wording in an alimony agreement?

We had a prenuptual. My husband deviated from the whole division of assets of what we aquired during our marriage. under duress from him telling me that if I do not accept his proposal, and if I make it public by contesting it, I could lose it all.I was afraid to pursue an attorney because I was afraid of what would happen. We settled- with him providing a "sweetened pot" quote-unquote(by him), by paying me three years more of alimony on top of the three years in the prenup. The agreement his attorney drew up was that he would pay me X amount of dollars for each year on February1..2013 was the fifth year. I married on April 24 '13. The agreement said that spousal support shall be terminalbe upon Wife's death, remarriage or cohabitation. I read that and personally understand that I will not receive the following year/(last year) of support. It does not state that I am to pay him back for what he paid me. He is taking me to court for reimbursement. ???Thank you
