What should I Do about this girl?

Ok Im 19 years old and about a year ago i met this girl that as soon as i seen her i knew right then and there i had to one way or another get her into my life. We talked gradually over the year but it progressed and progressed into a relationship. Now what makes this so substantial to me is that i have NEVER even thought that i could feel this much over ANYTHING, never the less a girl. Its just completly diffrent then past relationships...i feel different...shes just amazing. Well about 12 days ago....she calls me cryin saying she is so sorry and that im not gan wanna stay with her after she tells me something...so i told her just to say it....well she tells me she really only 16 years old when she told me she was 19.....she said the reason she lied about it is because she knew if i knew how old she was when we first started talking that i wouldnt talk to her no more. and see in past relationships i would get so mad whenever i was lied to. But with her....im not mad at all....im upset....the next day after she told me she got locked up for not going to school...so i havnt even really been able to talk to her about this....she gets out sunday morning and i just dont know what to say to her about....i dont want to leave her....thats the last thing i want to do....but i dont want her to think its kool to lie to me ya know. and see before she got locked up we were litterly inseperable. we practicly lived with eachother....everyday 24-7...and now that i have had all this time without her...i know i dont want to be without her.....what shud i do?
