How do I get her to like me?

she just got out of a relationship and she said she wants space on that type of level but then next minute she's kissing me, then she said she doesn't know what she wants.

All of that is an indication that she REALLY doesn't know what she wants and really does need time to get her feelings sorted out. There's nothing a person can do to make (or in other words, manipulate) someone like them.
