Why did my boyfriend break up with me ?

So we rented uhaul to go get our furniture and went for a viewing on the home , and his mother said we need to leave by September the 3rd 2019. We have been preparing to move out all month , then 3 days ago he started acting really weird and rude . He stopped talking to me for no reason . Even though we live in the same house . So i left to stay with my sister for a night and he texted me this .... What do you guys think .....
