help?

I fall for guys so easily it hurts. There's 2 guys that i've slept with and ever since, i developed feelings for both of them. I know they're fuckboys and i keep reminding myself of that but i still like them and get jealous when i see them with other girls. I've stopped talking to them and took them off social media and i still have feelings for them. How do i stop catching feelings so easily and/or how do i get over these guys?
