Confessions: My older boyfriend is too mean with his money

I am 17 and my boyfriend is 33 years old. I really love him and he always promises a good life ahead and that he will marry me. The only problem with him is that he is very mean with money and cannot even pay for my school fees. He hardly ever buys me anything even the simple presents boyfriends buy for their girlfriends. He always promises to pay my school fees but when the time comes, he becomes cold and avoids talking to me. Any discussion about money annoys him and makes things very difficult for us especially when he accuses me of being only after his money. He says he loves me very much but I am doubtful of this. I don’t know if to continue with him or not please help me decide on this.
