I've found this true for many women in general cheater or not. Being a former simp a lot of my simping was solicited by these women who were using me. They'd ask me to do things for them for the specific point of using me and feign a sort of relationship with me at the moment to get the favors.
a lot of them would later rationalize why it was ok to use me by saying things like "i didn't make you do that stuff you did it on your own." the truth was however they ask me for that shyt on their own taking advantage of the fact they knew I liked them and would do it when they really weren't all that into me.
I don't blame them but I see it as a character flaw. I would never knowingly use someone just because I knew they cared about me and would help me out. It's not justifiable in my eyes because I can handle myself. I don't need to use people for gain.
i'm the same way, i mentioned before im a nice person, i'll do things for people and not expect anything in return. the thing is it seems with women they will constantly abuse it. It's raining, pouring outside with lighting and thunder the grocery store is on your way so you take them, from then on every time they go grocery shopping they expect a ride from you.
