Help... I'm Confused?

Ok I have known this girl for awhile, over 4 years, and we have dated for a little over 2 years, on and off, right now we are not together, we have had our bumps in the road, and we never broke it off cause of anything we did to each other, but cause of family issues especially on her side, and im not her race, or follow her religion. She comes from a religion and race that im ok with but her parents would have a problem with me. They never knew that me and her dated but know me from when their daughter and I worked together. But she gets confused and breaks up, but we still have a attraction and love for one another, and she seems confused, but she moved about an hour away to start her new job, and she is still livin with family (btw, its kinda like lockdown, cant talk to men, cant go out.. etc) anyways, we have been intimate, and talked about various things like marriage and children. but now she doesn't really want to talk about things like that, we have been "broken up" for about 3 months, but we still keep in contact regularly, she calls, emails, and asks me questions. I want to see her and be with her, cause i love her, but if im too clingy she backs off, i only get clingy with her when she starts actin a certain way. she tells me that it will never work out, but she still talks to me constantly, and we met each other 2 weeks ago and we were intimate. So i don't know what to do, or how to approach this? A long time ago, she did something similar and i just kinda gave her, her space, and didn't contact her really, and she came back to me, and told me she wanted me back. Even now she crys to me and tells me that im the only one who makes her feel good, and have treated her right, and that she can tell me everything (and OMG she can talk..lol) So i am very confused myself and do not know what to do! Please any advice helps ! Thank you !
