Partner taking credit

My now ex-partner/ex-significant one helped me financially by paying for tech tools I needed to create a product. I did all the learning and all the hard work by myself, but now, when we are not together anymore, he claims that what I accomplished was due to him because he helped me financially. I never asked him. It was totally his choice and I could have paid for the tech tools myself. I feel angry with him because I think it is unfair. I thought he was paying because he loved me, but he was just to manipulate me, hoping that I would stay with him because of his money. I don’t like that he takes credit for something that was created by my hard work.
