<human>: Can you condense the text into three sentences or less?

I'm considering quitting my full-time job and finding something part-time instead while I focus on my part-time evening MBA program.

I took up a position as a production manager at a small company after relocating to Florida with my boyfriend. It's a new role they created after the previous web project manager left that was meant to encompass office management/accounting/project scheduling. I was excited at first since it was a much larger role than my job as a QA manager at a big e-commerce company. 

Long story short, things didn't turn out the way I thought they would. It's likely a result of me either not asking enough or the right questions during the interview. Either way, the team is entirely dysfunctional and is just barely getting through its production schedule despite efforts to work with individual developers on meeting deadlines/budgets. The devs basically try to circumvent their own manager whenever deciding on new approaches and their manager is so overbooked that he has no time to intervene or hold them accountable for missed deadlines ever. Also never teaches them anything or get everyone on the same page. Wonderful. /rant

Anyway, I stuck with it to at least give myself time to learn what I could and make myself useful even if the team was kind of toxic/uncooperative (I've definitely dealt with difficult people and still been able to get results!). I'm at 11 months (employment anniversary will be in March) but now I'm at the point where I've decided there's really no future for me there. Web development just isn't my industry, or at least it isn't with that team. I'm also never really going to advance - I report into the CEO.

My boss is fine with me pursuing my MBA so long as it doesn't affect my performance at work - originally I said it wouldn't. What's really affecting my work is my complete lack of drive or inspiration to even do the projects I signed for because I can't seem to make it work with the team. I don't want to stay there knowing the quality of my work will just go keep going down.
<bot>: What's the best way to tell my boss that I changed my mind and want to go part-time while going to school? Should I just be honest about not feeling like a good fit after nearly a year?
