I'm actually serious about this.
My problem began the other night when a girl commented on my mom's Facebook status. I'm literally friends with like 95% of the same people that my mom is, but I had no idea who this girl was. I creeped her Facebook and noticed that she was friends with my sister also. Wasn't having this, at all. We began talking through messages, and I found out who she was. I was heading to bed and told her to text me sometime and gave her my number. She texted me like 3 minutes later. We texted for a bit before she asked me for a picture of her, so I sent her one and she said I was "a cutiee

". I asked her for one in return, and she was surprisingly attractive.
Anyways, we began texting more frequently and everything, and shes all smiley faces and whatnot, and I'm all like "lol whateva". I really don't want anything from her romantically, I don't want to be in a relationship. But I also can't say "listen I'm not trying to talk to you like that", mostly because I understand the feeling of rejection all too well.
What do I do? :/
