Is a girl’s kindness often mistaken for romantic interest to guys?

There’s been guys that like me who I have no interest in that stop talking to me but eventually come back to talk after a few weeks, sometimes months thinking it will work this time around. No big deal to me I still talk to them as friends only. But when it’s a guy I like and he stops talking to me, I get confused. Then I realize how lousy I am at showing interest. I’m a very kind person and my girl friends have told me I act flirtatious when I’m not trying to be. So could these be correlated? Could I actually be confusing guys with my kindness and that causes them to stop talking to me for a while?
