Is an Aries girl more likely to be friends before lovers?

Ok, so there's this girl i chill with on the regular. I've been chillin with her for 2 years, maybe more. Anyways, i've always liked her from afar because i always kinda felt she was outta my league (she's SO hot and has this aura of sexiness about her.). but since we've been chillin, i've found that we have a lot of little things in common and agree on various different things plus we're both of the same religion, her parents really seem to like me too. i flirt with her here and there and she usually kinda acts like she's ignoring what i said even if it's blatantly as a joke. she's got this boyfriend who's a complete bum. let's just say he's had some bad "habits" in the past. they got a daughter together but their relationship as whole is in a downward spiral and it's quite obvious (her daughter loves me too btw.) with all that being said, i was chillin with her the other night, the boyfriend went out doing his own thing,so i just stayed n hung out with her, watched movies, she made me food which was really nice. so we get to talking and the conversation goes to me about my 5 year plan to move to California after i finish school and get my degree. She asks hypothetically if the situation happened where if i met someone, would i stay where i'm at now and not move to Cali? And i said Yes, i would stay if i met someone that i really liked. her response was basically repeating what i had just said as if she was contemplating on it. i swear sometimes she acts as though she likes me in that way but she's hard to read. and i'm not trying to ruin a good friendship cuz i got mixed signals or whatever. So, my question is, what do you guys think? am i over thinking the situation, or is there really something there that she's tryin to hint at but is unsure of her feelings. Just need a little insight n please only respond if you actually know what you're talking about. i'd prefer actual aries/cap relationships n such. there's a shit ton of generalizations on these sites.
