<human>: My girlfriend and I are both in high school, and we have been dating for about nine months.  We did not really know other before our relationship,  so during our relationship I learned a lot about her and her family. Here's where the problem comes in. 

I learned through getting to know them that her and her family make horrible financial decisions. At some points, my girlfriend repeatedly relied on me to pay for things fully including dinners, tickets to school functions, etc. 

I am done feeling like I am being used. I have made my decision, after many talks about money with her, that I do not want to be bogged down with this in college and I am going to break up with her before summer. 

 Next month is our graduation, and her birthday.  I tried to be a decent person and decided to make it through prom (She wanted to go. I paid for it).  I'm ready to break up, but I feel like an asshole if I break up with her before her birthday and our grad parties.  We're not sharing a party or anything but I was just wondering if anyone felt like it would be wrong doing it before these major events.

Give me the gist of the text in a nutshell
<bot>: I want to break up with my girlfriend as we both move on to college.  Is it rude if I do so before her birthday/ grad party?
