My girlfriend didn't say I love you back but ask for ten dollars. Am I wrong if I block her?

So I texted my girlfriend, "I love you," and she replied, "Night. Can I borrow ten dollars tomorrow?" I was speechless. She is always rude and insensitive toward my feelings, and making me feel vulnerable like that just to stump on my heart made me feel so dumb. I really felt like a moron for saying that. She always says I love you, but that one time was rude, and I had enough. Am I tripping?
