You have that too? I'm a female, and a few times guys who are not my type at all have claimed that I was interested in them.
I've only been in love only once in my life when I was 17, he was a gora and no Muslim and not in love with me, so nothing happened between us, that's it. I've never really been in love with anyone else after that, despite being married off to my cousin at the time. A few years ago liked a person a lot and thought I was perhaps finally in love (also a non-Muslim gora, go on, judge me... also not in love with me), but that didn't even come close to the feelings I had for the person when I was 17, so I don't think that really was falling in love. For the rest, nothing. Right now I'm in love with nobody. That's weird when I think about it. Now I should be asking myself what's wrong with me. Shouldn't people my age be in love with someone?
Various people have thought I was somehow romantically interested in them, just because I was friendly... but when you become unfriendly people hate it too. No matter what you do, if you are friendly or unfriendly, people will always get the wrong ideas about you.
Perhaps the people you talk to, aren't used to males and females talking nicely to each other without being romantically involved. Many people don't understand that males and females can be friends without any romance at all between them.
