First of all you need to pick yourself up and dust yourself off...you are not a door mat so stand up for yourself. You are too good and too easy to be used. Just because they are your bf's family doesn't make you their banker! Inform them you did what you could and it apparently wasn't good enough so you are done. You are standing up for yourself and don't owe them anything. Tell your bf you will not come between his family and himself but you are putting yourself first because it's what you deserve. Good luck, let them say what they want, it just shows what kind of people they are.
