I don't want to be with her anymore but not sure about some things. Help Please?

My girlfriend and I have been dating for a little over 5 months and been living together for 4 months. I know that sounds weird but we did know each other for almost a year before we started dating. We also said I love you to each other right after I moved in with her. For the first 4 months of our relationship I wanted nothing else but to be with her. But this past month I have no desire to be with her and have tried leaving her twice but she always gets me to stay. Always asks me to just try and give her a second chance. She completely changed the way she treats me after the first time I told her I didn’t want to be here anymore. Se before she always bossed me around and told me what to do, and I am not that type of person. I am very free spirited and independent. And I think that’s what finally drove me to not really be in love with her anymore. But I just lost my job a few weeks ago and haven’t been able to get another one yet and she has been bossing me around again. So I just think that the only reason that she wants me around is money. At least that is what it feels like to me. So I guess what I am asking is should I leave her or not? And if I do how do I do it without having a job or money right now? Is it wrong to just live with her till I find a job and can get my own place or is that just survival? I just need some reassurance on this and maybe some advice. Any comments or replies are greatly appreciated.
