canceling life insurance

financial adviser has advised me to ever universal life insurance. Even though i have paid premium for 25 years. Reason the cost of insurance each month is ever increasing and the monthly amount we are paying is no longer enough. so the cash accumulated is gradually going down. He feels that we are in a good financial position and no longer require life insurance. It is true that the cash built up is now going down and to keep it going up would require a greater cash pay each month. I dont know what to do.
