Here's a refined version of your message:
"Listen, what made you think that I'm the type of person you're looking for? As much as I’m intelligent, I'm not here to engage in mind games. I hear you saying that you're interested in me, but my real question is whether you are genuine about this. We live far apart, and don’t you have a girlfriend? I'm not the kind of girl you can just love and then leave behind. It’s clear that you have feelings for me, but are you truly ready for a serious commitment? Or do you just want to play games?"
