Important Dating Question and Situation

so, for all the men and women in the dating world, i'm sure you've come across a situation like this, and could use a little advice...

i was out at a bar with friends, me and my friends were invited back to her place where i hooked up with her...only made out with her. from there, i got her number and we talk A LOT! almost everyday we talk online, the phone or in person and have lunch or something.

since then, i've developed quite the crush on this girl...its weird, cuz before meeting her i was fine, now after meeting her and getting to know her, i think about her all the time and definitly want to work on a relationship with her. the problem is: she seems into me, she seems like she likes me and definitly hints at it, but then throws the whole thing for a loop, saying something like, "there's this guy, i really like, but i think i'm being played." when we hang out in person, she shows me a picture of him as well, what she would call a "boy toy."

a long story short, she's a girl that likes to have fun and is alright with being single, but wants a relationship at the same time, and at times it seems like she wants to pursue somethign with me cuz she likes me and at other times it doesn't and seems like she's into these other guys.

suggestions and/or comments on what i should do?
