Is space good for a relationship or will It ruin the relationship?

Me and my boyfriend recently moved in together and been arguing a lot. our last argument was really bad and he has been at his sister house for 8 days he's coming back home Sunday. we have been talking over text but it just seems like he's not that interested in me anymore he takes hours to respond to my messages he seems annoyed when I call him and our messages have been dry is that a sign he's over the relationship?
