I Can't Handle It Anymore

Hi, so I just posted in here a couple of days ago about a situation where I got kicked out of my house and brought very few belongings with me. I was staying at a motel until I was working closely with a co-worker of mine, who I'm not really compatible with, and I was stressed out about our work and told her a few details about my problem. She was pushy about getting me to come stay with her and made these promises like 'oh stay a month, save your money, don't contact your family, I'll help you get your stuff back' and it's been over a week. At first it was fine but she can be very controlling and irritable. She doesn't want to leave her house in the evening, when we're off work, and even though she said that I could use her computer, she stays on it with her boyfriend every night. She's also very impatient and testy at work and is kind of dismissive with things I bring up to her, even if it's work-related. The more time I spend with her, she seems kind of inconsiderate with other people and constantly goes 'well their problem isn't my problem.' I don't think she had the best intentions. Truth is I do have plenty of money saved up so I could leave on Monday, and stay with my cousin in Minneapolis who I've stayed with before. She also made sure I quit my job pretty quickly, and I just think she's passive agressive. Truth is she's never done this for anyone before, she doesn't have kids, I don't ask for anything and I mind my own business. I don't watch their tv, eat their food, or anything. Lately I've been riding with her to and from work but that's it. I told her I was taking the bus tonight (I actually want some space) and she went 'fine by me' in a condescending tone. Is it ok to ditch her and not say anything else? I don't feel comfortable with her.
