<human>: Condense the text into a few key points

So I've known my roommate for a year and a half now. I met him through college apartment housing. It's cheap rent able rooms with 3 other roommates and you have to live with them for a year. We instantly became good friends and had fun with no troubles for the year of our lease, halfway through that we agreed we know no one that's a better roommate choice than the other. A few months ago we signed a lease on a 1,100 apartment. My rent is 500 his is 600. I make about 1,400 a month and I have known my friend for a while and he has been nothing but responsible with his money. He met a girl two weeks ago and they instantly clicked, started hanging out with her every day, hey I figured it's just the honey moon phase. So tonight he tells me dead serious with his girlfriend he's moving in with her into her 1 bedroom place and his girlfriend's cousin is moving in. I don't mean to be judgemental but this cousin has been homeless for 2 years, maybe a year. I don't even know if he has a job all I know is that he has been sleeping at my roommate's girlfriend's place. And they went off to bed.

I am kinda freaking out right now since there is no way in hell I can afford the entire rent for even a single month.
<bot>: Roommate is moving in with his 1 week old girlfriend, dunno if I can afford rent by myself. This whole thing is insane I've known him for almost two years and he's seemed nothing but responsible since.
