Your husband is correct. The paint will not hold up well. Also, Painted counters do not really look all that good.
I wouldn't waist the time and effort to paint the countertops. If paint was any good, we would see factory painted countertops for sale in the home centers!
If you really cannot stand your counters, replace them. If you cannot afford to spend the money, wait and save up.
Just my opinion.
