Search Results: scaring a boy away

I work with this girl, she's really pretty and cute and she has the best personality. I can't say I REALLY like her, but the more time I spend with her the more I do.

Okay so, I think she likes me? I've been picking it up from little things she does. The problem is she is always so jokey and playful it can be hard to tell when she's being serious. Here's what she's done.
1. She's told me I have beautiful eyes.
2. She's told me my hair smells good.
3. She's told me she trusts me.
4. She's told me her mom really likes me.
5. She's told me she likes riding in the car with me.
6. She sticks her butt out whenever she knows I'll notice (and oh boy, do I notice!)
7. She pulls her shirt up to show her navel (I think to explain where she got burnt once or something)
8. She pulls her shirt up to show her navel just randomly. To itch or to readjust her shirt.
9. She runs over and hugs me whenever she hasn't seen me for a long time.
10. And the most confusing of all: she told me the guy she likes at her school finally kissed her.

Note: This is all over 6 months of working with her, and it's all said in her regular happy jokey voice/tone. Does she want me to get jealous? Is she just really playful? Should I ask her out? I'm scared to because I'm 18 and she's 16, plus I'm going to college on the other side of the country at the end of August (like 30 days away). Oh, and I've flirted back in between. I've told her I love how cynical she is, or how nice and long her hair is, or once she came in with her little siblings and I said "You guys get to hang out with her all day? Aw, I wish I could do that!" You know, flirting. She's pretty much kept up the same routine as mentioned above whenever I do that. Any help at all. I don't know if I'm the type of guy who is totally blind or one that thinks wishfully. Thanks, girls!
