He called her cutie, what the F!?!

I have been talking to this guy through texting and we don't live close to each other so we haven't hung out but we both agreed that we both liked each other but were not technically dating yet & he told me that he wouldn't hurt me & that he has fallen for me but I got on to Facebook & he commented on some girls page and called her cutie & was asking her how she was. I know I shouldn't care but I do it hurt. So why would he call her that when he likes me & do y'all think he is just messing with my feelings?
+1 y
Also should I say something about it to him?
