So I use to like but now I'm lost?

The girl I use to like from old school we still talk and on fb she called me cute and stuff but never did when I went to school with her we text and she broke with her bf the day I left so I thought she was trying to make me jealous and now she's going on about her new boyfriend is she trying to make me jealous or just showing her new bf off? I like someone else and every time I bring her up the girl I use to like doesnt reply to me unelse I change the subject?

If you "like someone else" and she has "new boyfriend," what's the problem? If you think she's playing mind games, leave her alone. It's unreasonable to expect other people to react the way you expect or want them to.
