When you are ”nice” and men automatically think you’re “flirting”

I really can’t stand it when some men automatically think you want something with them simply for being “nice” . I don’t go out of my way to be extra “nice” to people honestly. I am simply myself. I was raised right. I am well-mannered. I am kind and respectful of all people. My energy is the same toward males/females. I consider myself to be free-spirited but recently (before the pandemic) I found myself having to hold back bc some men think I’m “flirting” with them! I KNOW when I’m flirting with someone bc I am purposely doing it. But some men look for the tiniest instances to make up a whole story in their head about how you “want them”. I wish they would stop being so self centered and realize that NO I don’t want your dck! Just because I talk to you doesn’t mean I’m interested. And they really don’t know how to read body language AT ALL! Ex. They think you’re “flirting” so they try to make advances with you and even after you turn them down nicely, they keep trying to make moves. When I first notice this behavior I even start saying “dude, friend, man” (ex. what’s up dude?) & it is still not enough!! I wasn’t interested the first time you threw a cheesy pickup line at me, I am still not interested the 2nd time. Worst part is when you reject them, they say “then why lead me on?” I NEVER WAS!!! We were simply having conversations bc I THOUGHT men and women could be FRIENDS. I was treating you the way I treat all people! But since your mind revolves around sex, you think ANY woman is a chance at sex or some type of relationship. I hate that I had to hold back bc some men’s mindset is that ALL women are chasing after them or they feel the need to chase after any woman. The only thing I’m chasing after is a good career not your stupid attention. I recently joined this sub and I’ve learned that LVM can be of low value as boyfriends AND as friends. This sub has taught me not to hold back from being myself to accommodate to men under any circumstances. You THOUGHT I was flirting with you and now your feelings are “hurt” bc I’m not actually interested? Sounds like a personal problem.
