group projects

i am a very bad team-member. not because i'm not willing to do my part... i love to do my part. but it's more because i care more about my grade than my partner... so i do it all myself. because i know i will complete it. and i know i will do a good (enough) job.
i presently find myself in an awkward situation. we had a group project in one of my classes this semester, and it was a very big one. after the first couple of weeks and my partner wouldn't respond to emails, wouldn't look over the work i had done, showed up to meetings 30 minutes late... and came unprepared, i gave up. i hate conflict, so it was just easier to do myself.
i held back comments when she proudly stated that all of her other friends were freaking out about the project and it so wasn't a big deal (because i had been freaking out, too.) i let it slide when she said she was mad at me for demanding her recipe hand-out the day the project was due because -she didn't know it was due!-
however, today was our final in the class. our teacher was handing back our graded projects and said there were 2 groups she needed to meet with separately because of unequal team-work. whoops. and since i never mentioned all my pent-up frustration to my partner... she has no clue. (but should i really have to ask my partner IN COLLEGE to participate?) so now we have to MEET with my teacher about this. huh. and my partner decided that it couldn't be about team-work... it must be about something else. i am very frustrated, but at the same time, i kind of hope this whole problem just goes away :/
but seriously. it was a 20-something page project. and she did 4. 4 pages. out of 23? i am very frustrated
