Is OTHER wrong in the post ? POST : Backstory, she has a part time job where she works around 70ish hours every two weeks making about $14/ hour. 
She always complains about not having enough money, to the point where we decided I would pay more of the rent than her because I make more. 
She asks me to tell her what to do with her money because she says she bad with saving money and always over spends on thing. She never listens to me anyways so that doesn't matter. 

Story, her car kind of broke down so we budgeted $350 to pay for the mechanic. We don't have another car so he comes and picks her and I up because the cars done and we drive him back to the shop. She asked me for another $40 just in case earlier in the day, she already has $365, so I give it to her. When we get to the shop the mechanic says the total is $280 so instead of giving him the 280 or the 350 originally budgeted she gives him the entire $415 she had. On the way home I get mad at her for giving away money she doesn't have, she says I don't know shit and it would've been more at another mechanic. I tell her she obviously doesn't know shit either because she doesn't have the money to just be giving it away. 

So she dropped me off at home and she's driving around because shes mad at me for getting mad at her and now I just got a text from her saying I was being disrespectful and she doesn't want to be with me if I'm going to act like that. 

I don't feel like I did anything wrong but what do you guys think?
