How do i get over him

Iv caught feelings for my FWB. I cut him off and blocked him for 1 month. But just yesterday made plans to hang out with him this weekend. I already made plans even tho we hadn’t talked in awhile and i don’t know what to do. I like him but i know we wouldn’t work out. Should i ignore his texts and not show up? Or should i hook up with him to get it out of my system one more time and then leave him for good. Please help, any advice would be appreciated 😔
