I've been sorta dating this girl for six months right. I've spent nearly one thousand dollars on her given her all sorts of time and attention and she's strung me along without making me her boyfriend. So I haven't been seeing anyone else but her this whole time. I JUST went on a date with another girl last night and NOW the original girl after six months FINALLY "liked" the pictures of me on facebook...Is this like her weird way of trying to get me to go back to her (which I would totally do) or is she just messing with my head? And how should I approach her about it?
