All the signs point to this woman wanting to be with the neighbor, not you. She is taking you for a fool and does not love you. She can't even be woman enough to let you know she is no longer wanting you in her life. Maybe you are helping her pay for living expenses? This may be the only reason she is keeping you around right now.
Is there another friend you can stay with until you can get your own place? Do you work? Save all you can and get out as soon as possible.
