I can’t understand how to beat people who runaway all the time

So as the title says, I’m someone who always liked to learn how to be the aggressor in fighters and this isn’t anything new to me. Every fighter will have people playing turtle/scared do cheesy stuff and win a lot, in this game it’s no different but I feel like with all the negative frames and stuff it get extra confused and titled. I had a mai who all they did was back walk away from me and press buttons and they understood to not press a button while running away from me unless it hit to avoid a whiff punish. I need help understanding how in the world do I beat lame players when I’m walking forward and trying to counter hit their very obv attempt at walking away pressing a button while not whiffing at all. I feel like they use the opportunity of me walking forward to press a button, and I think I know that I’m supposed maybe just micro walk a little more ? I don’t know but I’m trying to play this game more because I wanna experience some friendship stuff with my friends and I’ll be honest i don’t like this street fighter for reasons I’m not gunna rant about because it’s probably been said a million times. I hope someone can help me understand some stuff, I main cammy but I wanna play manon because I like grapplers but they don’t even feel that good to play although manon has some great buttons. This is my ted talk.
