How do I deal with a jealous woman who needs constant validation?

I know I'm a bit old to be that inexperienced but it is what it is. So basically I'm dealing with a sort of jealous girl who needs me to confirm that I like her and that she's attractive to me often. And the weird thing is if I don't use the precise words she wanted to hear, she's gonna be pissed at me. How do I navigate that?
