<human>: So here's my situation. I rented a two bedroom, two bath apartment with another student who goes to my college. About in November, he had his homeless "friend" start to live with us, crashing on the couch (which I furnished) and generally bumming around. After a few months, I began to get fed up with it, obviously. 
Soon after this, I find a girl in my apartment, in my living room, with this older gentleman. At first, I thought it was just going to be a short "nightly" guest. She's been here for months too. I've talked to my roommate many times about how it is going to be a violation of the lease and I am not comfortable with it. He is also the cosigner and he signed a document agreeing basically to do whatever I say regarding the place.
His solution is to let them sleep in his walk in closet so they are not in my way and give them until August, when he will put a down payment for their place. I believe another 5 months is out of the question. Oh, a reminder: They haven't given me a cent. Much to the contrary, they actually have been eating my food and drinking my drinks.
At this point, I'm about fed up, and when I get back to college in a couple weeks I'm planning on having a conversation with my roommate about how I fear for our own living situation because of these two. (It isn't fair to compromise our own living situation for two grown ADULTS who can't handle themselves. I just turned 19 and I believe we have no reason to be responsible for them. If my roommate doesn't have them out when I tell him to, I plan on giving a tip to the leasing office of what my roommate has done.
I've been extremely patient but my patience has run extremely thin. How should I go about doing this? As bad as I feel about putting people on the streets, I really don't feel guilty seeing as we've done so much for them to begin with. My lease runs up in July and I might just tell my roommate that if they don't leave he can just move out and live with them, I'll have no problem finding a new roommate.

Summarize the given text in a few sentences.
<bot>: Homeless couple in my house, has been much longer than expected. Roommate insists on giving them more time, I disagree.
