How to break things off with my FWB?

Please no mean comments. I’ve had a friends with benefits for 3 years and I’m ready to break things off with him. I find myself thinking about him all the time and I’ve developed feelings. He’s been my only sexual partner the last 3 years and I’ve been his only one for last year. He stopped sleeping with other girls last year. I feel stupid for putting myself in a situation like this and will never do it again. I’ve learned my lesson and wouldn’t recommend a friends with benefits to anyone. How do I break things off with him? Our families are close so we are always going to be seeing eachother. Please help with what I should say to him I kind of want to make him feel bad lol. I know lots of you are going to say I don’t need an explanation but I believe I do. I want him to know I deserve better and am worth more than being used to sex. I just don’t know how to put everything into words
