Does she just want sex or does she want me?

It's a confused situation it really depends what is going on in her head, maybe all she does want is sex or maybe she does want a relationship but you never really can know, you got into a friendship relationship and soon after that use were friends with benefits maybe she doesn't know where her other feelings are coming from to actually take it a step further any be something more or maybe she is confused about the intensity of sex and the intensity of a relationship.
