Does she really love her boyfreind?!?!?!?

This is complicated... I really like this girl, and we have been good freinds for a year and a half. about 5 months ago we started going out, however it ended in about a month. She was very distressed over her ex boyfreind at the time and he took advantge of the situation. I used to be freinds with this jerk, but he really hurt her. Me and her talk for at least 2 hours a night, and are way closer than her and her boyfreind are. She even tells me this, but why is she still with him? Its blatantly obvious that he is with her because he doesnt wanna be alone. For some reason he hasnt made a ual advance on her, even though I know hes a horny pig! Even I've gotten further with her than that peice of trash! Anyways, About a week ago, I told her how I really feel, and she has been very open about herself since. She even told me that "shes been haveing thoughts about me that girls with boyfreids shouldnt have about other men". An incident happened the other day concerning tainted weed. Her and her boyfreind had smoked some **** and she doesnt remember about 2 hours of that time of the day, it turns out there was coc in it and she didnt know. According to her, her clothes were out of line and ****, but she didnt seem "d". I doubt he violated her, but we were still very worried about it. Me and her had gotton way closer last night. Tonight however was completely unexpected. First off, me and her talked for litteraly 6 hours today!!! She out of nowhere confessed to me everything about her life that nobody else knows, and most of which is pretty shocking and deeper than things she previously told me. She also made it extremely clear that absolutely nobody knows about what she told me, eeven her lousy boyfreind. She says that she loves him, but i dont think she means it. Why is she telling me these things? Am I too deep in the freinds zone? Does she want me over her boyfreind? I love her and only want her to be happy! What is going on!!!
