<human>: I have been living with my roommate, Jenna, since December. Our lease ends mid June and I'm not living with her again so I'm not sure if it's even worth talking to her about at this point. 

Jenna just started dating this guy, Mike, that comes to stay at our apartment every weekend. Jenna and I have shared groceries since we moved in together. I did not take into account that I would be feeding a future boyfriend too when we made this agreement. I do the majority of the grocery shopping, so it was annoying even before she started dating Mike. But now he eats everything so when I want something it's gone. For example: I wanted a bowl of cereal 20 minutes ago but nope...the gallon of milk I bought is gone. Okay...I'll make some eggs. Nope. Eggs are gone. Quesadilla? Ha! Think again. It doesn't help that I don't like the guy in the first place. I pay for my own groceries and I work on top of being a full time student. I don't have a car so it's not like I can just go and pick something up really quickly. 

Our lease is about to end in less than a month...is it even worth talking to Jenna about? How do I go about it without sounding super rude? Jenna is a decent roommate other than this.
