He makes his self mad just to leave

Okay so me and my fiance got into it last night we say with my mom and she can't take alot of stress so he decides to leave, and supposedly go stay with a co worker . When I asked him was he coming back today he said no,so I said I got my mind together and he asked In one day? The thing is what co-worker do u know is gonna just let u stay with them for days at a time? I don't know what to think. He can talk and text me on the phone but u don't wanna stay with me?Plus the last time he pulled this bullshit was on the same day thursday ,and the thing is he's acting so mad about something he started I think he just makes his self mad on purpose just to get away from me
