<human>: Today marks one week since he has not spoken more than a sentence to me. Out of the blue he stopped speaking to me. He can't be bothered to have a conversation even if it's small talk. He comes home. Puts his stuff on the counter and then goes to his room where he stays for the rest of the time. If I'm in the living room, he'll refuse to come out only until I go to my room. We just moved into a new place. Before, in our previous rental he would come home and we'd chill for a bit. Catch up with each other. He is now the complete opposite. I've tried talking to him but all I get are grunts and condescending remarks. I don't know what I've done to get this kind of reaction from him. I don't know how to fix it.

Can you give me the gist of the text in a nutshell?
<bot>: Roommate and I used to be great roommates. He now gives me a cold shoulder and wont talk to me at all.
