Should I text him?

Me and my boyfriend have been dating for 5 years. We got into a fight and broke up, we were trying to work things out but things are very uncertain. He told me he thinks we aren't going to change. I love him a lot and still want to be with him. We haven't talked for 4 days now, the last text I sent him was "maybe this is how we end.." and he never replied back. Im very unsure if we are together, working things out, or just done. Should I text him and clearify or move on?
