I'm In College And Want To Know If This Girl Likes Me.?

Ok so I've been after this girl for not too long now but may a month or two but anyway I really like her and want her to be my girlfriend and like idk something about her just clicks in my head telling me to go after her. She is graduating highschool this Friday and I want to go but I don't want her to think I'm obsessed with her or something you know but anyway sometimes we talk on the phone to each other and we can really click but what really gets me is like I'll text her and she won't text me back and then sometimes when I call she doesn't call back, and she doesn't even text me to say oh I'm sorry I missed your call or whatever I mean what the ****! But like I'm 19 she is 18 turning 19 in December this year and like she is a church girl she was raised by a Christan family and so was I and I can respect that she is into church and everything because I go to church every once in a while since I got a new job and I think another thing that attracts me to her is that we are both virgins now I'm not saying that I want to lose my virginity to her but I am saying that if It came down to it I wouldn't mind doing it you know. I'd be a Liar if I said that I didn't want to have sex with her or anybody else for that matter I mean just because you are like really religious and into whomever you worship doesn't mean people don't want to have sex, and she even admitted to wanting to have sex but she said temptation whatever but anyway can somebody please answer my question I would really appreciate it a lot guys Thanks again.
