Until I graduate I'm going to  be using my boyfriend for his money.
That does not sound good. How much money are you talking about?
Lots of money.
To try and use someone for their money is very pathetic. You should never be dating someone just to try and get to their money. If you don't love the person you're dating then you should think about breaking up with them.
I think it's about time that we broke up then.
It might be, it would not have been fair for your boyfriend to be used for money. You should have more self-worth than to sell yourself for money.
