Possibly.
If she texts right back.
that means she likes you
ask her if she does and if she texts you about almost everything when its nothing
Playing hard to get.
Text him and ask why he's still with the other girl. If he says, "She's hot..." Just ask him, "Why are you wasting your "date time" calling and texting me?"
That he still cares & possibly likes the girl still
Well, being that I'm a girl i can answer this question for you easily. If you're texting a girl and she texts you back she likes you on some level. So you're one point up there. When you're texting a girl and she texts you back a sentence or more that means she wants to talk to you. If she's texting you and suggests that you call her she likes you. Also, if you have feelings for a girl it will definitely show in your text message. It's better to get to know a girl in person though.
She likes to be mean and/or fierce in a nice way:)

Ask her.
You can still make the relationship work,most people attend different schools from the person they're dating.
If she is still agreeing to go out with you she probably likes you.
