Guy's Behavior

She would date me if she was single.

I like a girl.. Paige.. She has an awesome personality a bit.. high schoolish.. but this is completely understandable.. as she's in high school and I'm a somewhat recent graduate.. I'm really attracted to her.. in looks and personality. She has a boyfriend.. Now.. this is where it gets a little.. eh.. When I first met her.. I didn't know about her boyfriend for one month or so.. so I got to liking her a lot long before I knew.. then one day I found out and was pretty much like.. you have got to be kidding me.. On the other hand.. she likes me.. I just know she does.. she's told me.. she would date me if she's single.. and she wishes she could have more than one boyfriend.. which wouldn't work as I pointed out.. but I get what she's saying there.. she likes me.. and as far as I can tell her boyfriend too.. but he was there first and all.. Well they don't see each other very much.. she can drive.. he cannot.. and his parents are "Nazis" as in they pretty much don't much like her I guess. and he rarely spends time with her.. she's annoyed by this.. but has dealt with it.. OK there is the situation.. in a nutshell.. now to the current problem.. I originally as soon as I found out she had a boyfriend.. pretty much just cursed a lot and kinda kept my distance.. but it has been extremely hard.. as she's kinda lightly flirts.. and when I look into her eyes.. she just looks right back and if nothing happens.. I think we could get stuck like that.. haha.. anyhow.. recently.. she wanted to hang out.. as friends and I said sure.. a few days passed.. and I found that I was not doing anything one day.. so I asked if she wanted to hang.. and she said sure.. now this evolved from just sitting around her house.. to going to the mall.. so she could get out.. Apparently.. boyfriend found out.. and got really really p*ssed off.. and I feel quite bad actually.. I don't want him to feel like I want her to cheat on him.. she would never do that and I wouldn't let her anyway.. well there kinda in a fighting era.. where she's getting all stressed out.. about I guess all kinds of stuff.. she's talked about how he never seems to try to do things with her.. it's always her initiating and then it not happening.. so she was wanting him to do something.. and he wasn't so when I asked if she wanted to hang.. she said sure.. We had a good night.. we walked all around the mall.. talked the whole time we were there.. which was like.. a few hours.. got ice cream and such.. I got her back home at a reasonable time.. and then the next day I told her.. I woke up so happy.. and she said she did too.. and then thinking about each other throughout the day and such.. So OK.. I know she likes this other guy.. and they are in a rough spot.. I want to know.. since I really like.. her.. if I should try to just be there for her.. or just kinda leave it be.. I'm afraid that if I try to be there.. I get stuck as a friend.. but if I don't then I possibly loose any chance.. what should I do?

I should add.. After I backed off.. we continued to lightly flirt a bit.. then.. we stopped working together a lot.. and for like two weeks.. I didn't see or talk to her.. then I just get a "I miss you" text one day.. this led up to ^ this.

I have mostly had this resolved.. last night she told me she really likes me.. and she was sorry for making me sad.. as I got into a bit of a lame out.. and started feeling poopy thinking I would never have a chance with her. Apparently.. I do..
