WIBTA (20M) for breaking up with my gf (20F)?

We’ve been together for 7 months now, and I’ve come to realize that this might not work out. I realized that I put in way more effort than her, such as cooking, driving, paying for dates, planning dates, etc. She bought me clothes once, gave me a gift a couple times, paid for barely any dates. She forgot to give me an anniversary gift for the past 3 months, even though she’s the one who wanted to celebrate monthly. I always give her flowers, never missed a month. It makes me feel not appreciated, which I mentioned to her months ago, but I don’t see any increase in effort. Recently she’s been lied to giving her SSN to create an Amazon FBA account for someone overseas. I told her to stop immediately, but she said she’s willing to “take the risk,” which I think it’s pure ignorance. If you’re not willing to listen to me then why am I even here? What should I do, because I don’t even feel like trying anymore. She stopped putting effort and attention, and I’ve tried to change her.
