Living with your landlord problems! Please comment:/ very hungry

I'm in my 34th week. And I'm not working. Me and my husband rent out a room in his friends house. Well the woman works during the day but her husband hasn't been working and he has been at home pretty much all day. We have this unspoken rule in the house that while somebody is cooking and eating that the other family let's them have their privacy and will not go into the room unless they seriously need something or is just passing through the room. Well her husband has been spending time in the kitchen basically all morning..just sitting and listening to music and walking around. And his wife and her brother just got off of work around 1pm...they have been in the kitchen ever since! And its 3:00pm!!! I'm hungry!! I only had a small bowl of cereal and a banana this morning and I'm starving to death! And it doesn't even sound like they are almost done. They are just sitting at the table eating and talking... I do t see why its taking them so long. They know I'm home! And I'm starting to lose my patience.. Last time I walked in the kitchen to cook while they were eating they had "a talk" with my husband and threatened to kick us out... What am I suppose to do. Its not like I can just walk to the store or go out to eat cause my husband uses the car to go to work. What am I suppose to do? I can't wait until my baby is born so I can move out!! We are moving out of state two weeks after she is born..so I will finally be living my myself and have them out of my hair!! But until then...what am I to do?
