You are NOT weak. What you are experiencing is love for someone else but it does appear as if Train's advice might be your best option at this time.
But it [censored]. If I was in your position I would do what Train said. I may be in that same situation but I seem to be getting more positive interactions (not just words, but actions) from W. You are dealing with a lot of open disrespect towards you and while you may have fear and hurt at the end of the day you may be better off doing what Train said and MAYBE H will recognize he is being an [censored] and try to be better (at which point you of course need to wait and see him being better on a consistent basis)
On a different level: I work on a college campus. If you end up in a very negative financial situation a lot of universities waive tuition for homeless students and have other accommodations for financial hardship. As a professor myself if the texts are too expensive come talk to us. We often have an extra copy or will get it for you. There may be extensions on assignments. Not all of us will work with you but a lot of us understand these situations. In fact, ironically I have helped a ton of female students get out of abusive and hostile relationships by accommodating their schedule. I say ironically, because turns out I was not an ideal H either.
But please whatever happens don't sell your own dream short in pursuing that degree. That is something you work hard for and will have earned. (And here is where I get sad because I recognize I didn't tell my own W this about her dreams of pursuing a PhD and focusing too much on making the financial picture work. I thought she can do it later.)
